Definitions
- the present invention relates to microfluidic devices, and more particularly to heat management in such devices.
- Microfluidic devices are known.
- U.S. Pat. No. 6,130,098 (“the '098 patent”) (the contents of which are incorporated herein in their entirety by reference) discloses microfluidic devices that include microdroplet channels for transporting fluid droplets through a fluid processing system.
- the system includes a variety of microscale components for processing the fluid droplets, including micro-reaction chambers, electrophoresis modules, and detectors (such as radiation detectors).
- the devices also include air chambers to internally generate air pressure to automatically withdraw a measured volume of fluid from an input port.
- these elements are microfabricated from silicon, glass, ceramic, plastic, and/or quartz substrates.
- the various fluid-processing components are linked by microchannels, through which the fluid droplets flow under the control of a fluid propulsion mechanism.
- the substrate is formed from silicon, electronic components may be fabricated on the same substrate, allowing sensors and controlling circuitry to be incorporated in the same device. Since all of the components are made using conventional photolithographic techniques, multi-component devices can be readily assembled into complex, integrated systems.
- Microfluidic devices use heating elements to accomplish a variety of tasks.
- U.S. Pat. No. 6,130,098 discloses devices that use heating elements to automatically withdraw a measured volume of fluid from a fluid input port. Liquid placed into a fluid port flows into a channel, past a chamber connected to the side of the channel, and stops at a hydrophobic patch on the wall of the channel. The chamber is then heated, causing pressure to build up. Once the pressure reaches a particular threshold, a microdroplet splits from the rest of the liquid, and is pushed over the hydrophobic patch and down the channel for further processing.
- Heating elements can also be used to move such a measured microfluidic droplet through an etched channel. This can be accomplished using a heat-controlled pressure chamber as described in the '098 patent. Fluid movement can also be performed using a series of heaters to generate thermal gradients to change the interfacial tension at the front or back of the droplets, thereby generating a pressure difference across the droplet. For example, a droplet can be propelled forward by heating the back interface. The local increase in temperature reduces the surface tension on the back surface of the droplet and decreases the interfacial pressure difference. The decreased pressure difference corresponds to an increase in the local internal pressure on that end of the droplet. The two droplet interfaces (front and back) are no longer in equilibrium, and the pressure difference propels the droplet forward. Forward motion can be maintained by continuing to heat the droplet at the rear surface with successive heaters along the channel (see FIG. 5 of U.S. Pat. No. 6,130,098), while heating the opposite surface can be used to reverse the motion of the droplet.
- heater elements may be used to control the temperature in reaction chambers, for example, to perform PCR.
- Others may be used to manipulate valves made of meltable material (such as wax or solder) as described in U.S. Pat. No. 6,048,734.
- All such heater elements when heating a particular region of a microfluidic device, tend to generate unwanted heat in other regions of the device. Such unwanted heat may adversely affect operation of the microfluidic devices. For example, too much heat can adversely affect the properties of a liquid or gas being processed.
- the invention relates to a system and method for preventing or reducing unwanted heat in a microfluidic device while generating heat in selected regions of the device.
- the invention involves supplying current to a heating element through electric leads, wherein the leads are designed so that the current density in the leads is substantially lower than the current density in the heating element. In a preferred embodiment, this is accomplished using conductive leads which have a cross-sectional area which is substantially greater than the cross-sectional area of the heating element.
- the invention involves reducing the amount of unwanted heat in the microfluidic complex by thermally isolating the electric leads from the microfluidic complex.
- this is accomplished by running each lead directly away from the microfluidic complex, through a thermally isolating substrate. After passing through the thermally isolating substrate, the leads are then routed to the current source.
- the thermally isolating substrate substantially blocks the transfer of heat from the leads to the microfluidic complex.
- the invention involves removing unwanted heat from selected regions of the microfluidic complex using one or more cooling devices.
- one or more Peltier cooling devices are attached to a substrate to remove heat generated by heating elements and/or other electronic circuitry.

- the present invention relates to microfluidic devices, and in particular, heat management in such devices.
- Microfluidic devices typically include micromachined fluid networks in an integrated analysis system. Fluid samples and reagents are brought into the device through entry ports and transported through channels to a reaction chamber, such as a thermally controlled reactor where mixing and reactions (e.g., restriction enzyme digestion or nucleic acid amplification) occur. The biochemical products may then be moved, for example, to an electrophoresis module, where migration data is collected by a detector and transmitted to a recording instrument.
- the fluidic and electronic components are preferably designed to be fully compatible in function and construction with the biological reactions and reagents.
- FIG. 1 shows an expanded view of a simple microfluidic device, which will be used to illustrate some of the heat management techniques of the present invention.
- the device includes an upper substrate 120 , which is bonded to a lower substrate 127 to form a fluid network (see FIGS. 2-4 ).
- the upper substrate 120 depicted in FIG. 1 is preferably formed of glass and has a microfluidic complex 110 in its bottom surface 112 .
- substrates composed of silicon, glass, ceramics, plastic, and/or quartz are all acceptable in the context of the present invention.
- Microfluidic complex 110 includes a plurality of chambers connected by a network of microchannels.
- the number of chambers and channels, as well as the overall topology of the microfluidic complex, will depend upon the particular application which the microfluidic device is designed to perform.
- FIG. 1 depicts a simple microfluidic complex for purposes of illustrating the heat management techniques of the present invention, and is not intended to depict a microfluidic complex for any particular application.
- the channels and chambers of the microfluidic complex are etched in the bottom surface 112 of the glass substrate 120 using known photolithographic techniques. More specifically, transparent templates or masks containing opaque designs are used to photo-define objects on the surface of the substrate.
- the patterns on the templates are generated with computer-aided-design programs and can delineate structures with line-widths of less than one micron. Once a template is generated, it can be used almost indefinitely to produce identical replicate structures. Consequently, even extremely complex microfluidic complexes can be reproduced in mass quantities and at low incremental unit cost.
- the lower substrate 127 includes a glass base 130 and an oxide layer 150 . Within oxide layer 150 , resistive heaters 140 and electric leads 160 are formed. The leads 160 connect to terminals 170 which are exposed at the edge of the substrate to permit electrical connection to an external voltage source (not shown) that controls the heaters. More specifically, to activate a heater 140 , a voltage is applied across a pair of terminals 170 to supply current through leads 160 and heater 140 , thereby heating the resistive heater element 140 . However, since the same current passes through leads 160 , these leads are also heated.
- Metal heater elements 140 are positioned so that, when the upper and lower substrates are bonded together, the heaters reside directly beneath the fluid chambers of the upper substrate so as to be able to heat the contents of the microchambers.
- the silicon oxide layer 150 prevents the heating elements 140 from directly contacting with fluid in the microfluidic complex 110 .
- the oxide layer 150 , heating elements 140 , and resistive leads 160 are fabricated using well-known photolithographic techniques, such as those used to etch microfluidic complex 110 .
- FIG. 2 is a top-down view of the device in FIG. 1 .
- upper substrate 120 is shown atop substrate 127 and silicon oxide layer 150 .
- Each microchamber 125 of the microfluidic complex is directly above a corresponding heater element 140 to allow the heater to raise the temperature of the contents of the chamber. (This relationship is shown more clearly in the cross-sectional end view of the device depicted in FIG. 3 ).
- the leads 160 (which supply current to the heaters) pass directly beneath microchannel 115 . This relationship is more clearly shown in cross-sectional side view of the device depicted in FIG. 4 .
- FIG. 4 clearly shows the leads 160 positioned beneath microchannel 115 and separated from the channel 115 by only a thin layer of oxide.
- the leads 160 when carrying current to heater 140 , may warm any fluid (or gas or meltable material) in the microchannel 115 , thereby possibly adversely affecting the operation of the microfluidic device.
- the heater leads 160 also run close to the channels connecting chambers 125 to channel 115 . Accordingly, when the leads are supplying electric current to heater 140 , they may also unintentionally warm the contents of any fluid or wax in the side channels.
- FIGS. 5-7 depict the structure of a first preferred embodiment of the invention which eliminates, or at least substantially reduces, such unwanted heat from the leads.
- the resistive heating elements 540 reside in the oxide layer directly beneath chamber 125 , just as they do in the structure shown in FIG. 2 .
- the electrical leads do NOT reside in the oxide layer 150 .
- the leads 565 first pass directly through the oxide layer 150 and glass base 130 to the opposite side of the substrate 130 (herein “vertical leads”).
- the vertical leads 565 are orthogonal to the plane in which heater elements 540 reside.
- the vertical leads 565 are then connected to horizontal leads 560 , which run along the opposite side of substrate 130 and connect to terminals 570 as shown in FIG. 7 .
- horizontal leads 560 run under channel 115 .
- Base 130 and oxide 150 should collectively have a sufficiently low thermal conductivity to substantially prevent heat emitted by the leads on the bottom of substrate 130 from adversely affecting the operation of the microfluidic complex 110 .
- this configuration substantially reduces the amount of heat transmitted from the leads 560 to the microfluidic complex 110 .
- the above described technique is not limited to microfluidic devices formed from a pair of substrates, such as shown in Fig. Rather, the technique is generally useful in microfluidic devices for reducing unwanted transfer of heat generated by the electric leads. Regardless of how the microfluidic complex is formed, unwanted heat transfer is reduced if the electric leads are routed from the terminals of the heating element through a thermally resistive material, such that the leads are substantially isolated from the microfluidic complex.
- the vertical leads shown in FIGS. 5 and 6 may be formed by drilling holes through substrate 130 before oxide layer 150 and heater 540 are formed.
- such holes are 200-500 ⁇ m in diameter, but it should be understood that the size of or method of constructing the hole may vary.
- Preferred means for drilling the holes are related to the desired diameter. For holes 300 ⁇ m and greater, mechanical drilling or ultrasonic drilling is preferred, although laser drilling also works. Laser drilling presently works for holes as small as 200 ⁇ m in diameter; recent research indicates that laser drilling may also work for holes as small as 50 ⁇ m in diameter, or smaller.
- Leads 565 may be run through the holes either by electroplating or by squeezing conductive materials (e.g., pastes) through the holes using screen-printing techniques.
- conductive materials e.g., pastes
- Materials for electroplating include aluminum, gold, and nickel, as known in the art.
- Materials for conductive paste include silver-filled epoxy, although other pastes are known to those skilled in the art to be appropriate.
- An alternative method of creating the vertical leads 565 is to form a substrate that comprises a “grid” of vertical leads, such as shown in FIG. 18 .
- a “lead-gridded” substrate 1810 is preferably fabricated by stretching a plurality of wires through a tabular shaped mold 1710 , with the wires spaced in the same spacing desired for the intended leads.
- the leads can be laid out in a rectangular matrix, for example, and the heater leads run to the nearest pair of vertical leads).
- a substrate material such as plastic is injected into the tube 1710 (or an elongated quadrilateral or another shape appropriate to the method described herein) and surrounds the wires 1720 .
- the result is a cylinder of substrate material comprising wires 1720 that run parallel to the axis of the tube and that are spaced cross-sectionally as the vertical leads are desired to be spaced in the substrate. See FIG. 17 .
- the remaining steps are to slice the cylinder into a cross-section 1810 of the desired thickness and polish as necessary. See FIG. 18 .
- Those skilled in the art will recognize the cost efficiency of this method, in that multiple lead-gridded substrates (of uniform or varying thicknesses) can be obtained from a single wired cylinder of the type shown in FIG. 17 .
- unwanted heat transfer from the leads to a microfluidic complex 110 may also be reduced by substantially decreasing the current density in the leads relative to the current density in the heating elements.
- this is accomplished by providing the leads with a greater thickness than the conductors of the heater element 540 .
- the leads 1360 are substantially thicker than the conductor which forms the heating element 540 .
- Increasing the vertical thickness of the lead wires increases the cross-sectional area of the lead wires, thus decreasing the electrical resistance of the wires. This also decreases the current density within the leads and thereby decreases the amount of heat radiated by the leads when a given current is applied.
- heat transfer from the leads to a microfluidic complex 110 may also be reduced by increasing the horizontal thickness of the electric leads 1660 that connect heater elements 540 to a power source.
- “horizontal” means in a direction parallel to the plane in which oxide layer 150 lies (refer to FIG. 15 , for example).
- the leads 1660 have a length taken along a dimension d l , which is parallel to the plane in which oxide layer 150 lies.
- Leads 1660 are thicker than heater element 540 along a dimension d w , which is parallel to the plane in which oxide layer 150 lies and orthogonal to dimension d l , of the leads.
- the preferred configuration is similar to that shown in FIGS. 2-4 .
- the improvement comprised in the embodiment shown in FIG. 16 lies in the increased horizontal thickness of leads 1660 .
- Increasing the horizontal thickness of the leads increases the cross-sectional area of the lead wires, thus decreasing the electrical resistance of the wires. This in turn decreases the amount of heat radiated by the wires when a given current is applied, thus decreasing the amount of heat transferred from the wires to microfluidic complex 110 .
- An advantage of increasing the horizontal thickness instead of the vertical thickness is that there is less likely to be a need to increase the thickness of the oxide layer 150 .
- an advantage of increasing the vertical thickness instead of the horizontal thickness is that a greater number of leads can be used on the substrate without interfering with each other.
- the thickness of the leads is increased in both the horizontal and vertical directions.
- the leads can be modified in a variety of ways without departing from the scope of the invention, as long as it results in a substantial decrease in the current density within the leads (relative to the current density in the heating elements) to thereby reduce the amount of heat transferred from the leads to the microfluidic complex to an acceptable level (i.e., a level that does not significantly interfere with the operation of the microfluidic complex).
- the vertical feed through shown in FIGS. 5-7
- the thickened leads FIGS. 13-16
- the leads 565 see, e.g., FIG. 7
- the leads 560 see FIG.
- substrate 130 can also be increased in thickness to reduce heat emitted by the leads 560 that could be transmitted to the microfluidic complex 110 , although preferably the substrate 130 is comprised of material with a thermal conductivity low enough to make such a modification unnecessary.
- the amount of heat in a microfluidic complex may also be controlled using one or more Peltier devices. See FIGS. 8-12 . Such devices can be made to act as heat pumps, removing unwanted heat from a microfluidic complex or component thereof.
- Peltier devices are well-known (see U.S. Pat. No. 5,714,701, to Chi et al., for example). Peltier discovered the effect that bears his name in 1834.
- Modem Peltier devices also known as thermoelectric cooling devices
- At least one Peltier device 810 is attached to the substrate 130 , although in an alternate embodiment at least one Peltier device 910 (see FIG. 9 ) is attached to the upper substrate 120 of a preferred microfluidic device.
- This “upper” Peltier device 910 can be in addition or an alternative to any “lower” Peltier devices 810 attached to the substrate 130 .
- Preferred Peltier devices are battery-operated, and are attached to substrate 130 or substrate 120 using a heat-transfer paste, to improve heat conduction.
- a Peltier device is used to cool an entire microfluidic chip. As discussed below, Peltier devices are used in other embodiments to cool selected areas of a chip, sometimes cooling different areas at different times, depending on the preferred operation of a microfluidic complex in the chip.
- Peltier devices are preferably used to remove heat primarily from selected areas of a microfluidic complex. For example, unnecessary power consumption would result if a Peltier device was cooling the entire substrate at the same time that a heater element was attempting to heat a selected chamber in the substrate.
- a plurality of Peltier devices controlled electronically, heat can be removed from selected areas of a microfluidic complex while allowing other areas to be heated with a minimum of consumed power.
- FIG. 10 shows two Peltier devices 1010 attached to the bottom of substrate 130 so as to be capable of cooling selected areas (microchambers 125 ) of a microfluidic complex in substrate 120 .
- the depicted configuration is, of course, merely exemplary—any operable configuration of multiple Peltier devices, where the Peltier devices are of any compatible collection of shapes, would also work in this embodiment.
- a multiple-Peltier-device configuration can also be used on a microfluidic device such as that depicted in FIGS. 2-4 .
- Multiple Peltier devices 910 can be similarly configured on the top substrate 120 of a microfluidic device. Peltier devices can be used to cool an entire microfluidic chip, an entire microfluidic complex, or selected portions (channels, chambers, etc.) thereof, and different Peltier devices can be used at different times, depending on desired functionality of the microfluidic complex.
- FIGS. 11 and 12 depict cross-sectional views of the device in FIG. 10 .
- a silicon oxide layer 1150 covers heater leads 560 .
- a heat-transfer paste lies between silicon oxide layer 1150 and Peltier devices 1010 .
- the present invention contemplates more complicated devices involving the introduction of multiple samples and the movement of multiple microdroplets (including simultaneous movement of separate and discrete droplets), as well as multiple microchannels and microchambers, and potentially including meltable materials.
- the subject invention is not limited to microfluidic devices comprised of one glass substrate bound to another, or to microfluidic complexes formed by etching or otherwise forming chambers and channels into the bottom surface of an upper substrate that is then bonded to a lower substrate, or even to microfluidic devices formed by bonding one substrate to another.
- the present invention will be recognized by those skilled in the art as applying to any microfluidic device that comprises a microfluidic complex having a heating region.
Abstract
A system and method for preventing or reducing unwanted heat in a microfluidic of the device while generating heat in selected regions of the device.
In one example, current is supplied to a heating element through electric leads, wherein the leads are designed so that the current density in the leads is substantially lower than the current density in the heating element. This may be accomplished using conductive leads which have a cross-sectional area which is substantially greater than the cross-sectional area of the heating element.
In another example, unwanted heat in the microfluidic complex is reduced by thermally isolating the electric leads from the microfluidic complex. This may be accomplished by running each lead directly away from the microfluidic complex, through a thermally isolating substrate. After the leads pass through the thermally isolating substrate, they are then routed to the current source. Thus, the thermally isolating substrate substantially blocks the transfer of heat from the leads to the microfluidic complex.
In another example, unwanted heat is removed from selected regions of the microfluidic complex using one or more cooling devices. One or more Peltier cooling devices may be attached to a substrate to remove heat generated by heating elements and/or other electronic circuitry.

- 1. Field of the Invention
- The present invention relates to microfluidic devices, and more particularly to heat management in such devices.
- 2. Description of the Related Art
- Microfluidic devices are known. For example, U.S. Pat. No. 6,130,098 (“the '098 patent”) (the contents of which are incorporated herein in their entirety by reference) discloses microfluidic devices that include microdroplet channels for transporting fluid droplets through a fluid processing system. The system includes a variety of microscale components for processing the fluid droplets, including micro-reaction chambers, electrophoresis modules, and detectors (such as radiation detectors). In some embodiments, the devices also include air chambers to internally generate air pressure to automatically withdraw a measured volume of fluid from an input port.
- Typically, these elements are microfabricated from silicon, glass, ceramic, plastic, and/or quartz substrates. The various fluid-processing components are linked by microchannels, through which the fluid droplets flow under the control of a fluid propulsion mechanism. If the substrate is formed from silicon, electronic components may be fabricated on the same substrate, allowing sensors and controlling circuitry to be incorporated in the same device. Since all of the components are made using conventional photolithographic techniques, multi-component devices can be readily assembled into complex, integrated systems.
- Microfluidic devices use heating elements to accomplish a variety of tasks. For example, U.S. Pat. No. 6,130,098 discloses devices that use heating elements to automatically withdraw a measured volume of fluid from a fluid input port. Liquid placed into a fluid port flows into a channel, past a chamber connected to the side of the channel, and stops at a hydrophobic patch on the wall of the channel. The chamber is then heated, causing pressure to build up. Once the pressure reaches a particular threshold, a microdroplet splits from the rest of the liquid, and is pushed over the hydrophobic patch and down the channel for further processing.
- Heating elements can also be used to move such a measured microfluidic droplet through an etched channel. This can be accomplished using a heat-controlled pressure chamber as described in the '098 patent. Fluid movement can also be performed using a series of heaters to generate thermal gradients to change the interfacial tension at the front or back of the droplets, thereby generating a pressure difference across the droplet. For example, a droplet can be propelled forward by heating the back interface. The local increase in temperature reduces the surface tension on the back surface of the droplet and decreases the interfacial pressure difference. The decreased pressure difference corresponds to an increase in the local internal pressure on that end of the droplet. The two droplet interfaces (front and back) are no longer in equilibrium, and the pressure difference propels the droplet forward. Forward motion can be maintained by continuing to heat the droplet at the rear surface with successive heaters along the channel (see FIG. 5 of U.S. Pat. No. 6,130,098), while heating the opposite surface can be used to reverse the motion of the droplet.
- Other heater elements may be used to control the temperature in reaction chambers, for example, to perform PCR. Others may be used to manipulate valves made of meltable material (such as wax or solder) as described in U.S. Pat. No. 6,048,734.
- All such heater elements, when heating a particular region of a microfluidic device, tend to generate unwanted heat in other regions of the device. Such unwanted heat may adversely affect operation of the microfluidic devices. For example, too much heat can adversely affect the properties of a liquid or gas being processed.
- The invention relates to a system and method for preventing or reducing unwanted heat in a microfluidic device while generating heat in selected regions of the device.
- In one aspect, the invention involves supplying current to a heating element through electric leads, wherein the leads are designed so that the current density in the leads is substantially lower than the current density in the heating element. In a preferred embodiment, this is accomplished using conductive leads which have a cross-sectional area which is substantially greater than the cross-sectional area of the heating element.
- In another aspect, the invention involves reducing the amount of unwanted heat in the microfluidic complex by thermally isolating the electric leads from the microfluidic complex. In a preferred embodiment, this is accomplished by running each lead directly away from the microfluidic complex, through a thermally isolating substrate. After passing through the thermally isolating substrate, the leads are then routed to the current source. Thus, the thermally isolating substrate substantially blocks the transfer of heat from the leads to the microfluidic complex.
- In another aspect, the invention involves removing unwanted heat from selected regions of the microfluidic complex using one or more cooling devices. In a preferred embodiment, one or more Peltier cooling devices are attached to a substrate to remove heat generated by heating elements and/or other electronic circuitry.

- Microfluidic devices typically include micromachined fluid networks in an integrated analysis system. Fluid samples and reagents are brought into the device through entry ports and transported through channels to a reaction chamber, such as a thermally controlled reactor where mixing and reactions (e.g., restriction enzyme digestion or nucleic acid amplification) occur. The biochemical products may then be moved, for example, to an electrophoresis module, where migration data is collected by a detector and transmitted to a recording instrument. The fluidic and electronic components are preferably designed to be fully compatible in function and construction with the biological reactions and reagents.
- There are many formats, materials, and size scales for constructing such integrated micro-fluidic systems.
FIG. 1 shows an expanded view of a simple microfluidic device, which will be used to illustrate some of the heat management techniques of the present invention. The device includes anupper substrate 120, which is bonded to alower substrate 127 to form a fluid network (seeFIGS. 2-4 ). - The
upper substrate 120 depicted inFIG. 1 is preferably formed of glass and has a microfluidic complex 110 in itsbottom surface 112. Those skilled in the art will recognize that substrates composed of silicon, glass, ceramics, plastic, and/or quartz are all acceptable in the context of the present invention. -
Microfluidic complex 110 includes a plurality of chambers connected by a network of microchannels. The number of chambers and channels, as well as the overall topology of the microfluidic complex, will depend upon the particular application which the microfluidic device is designed to perform. However,FIG. 1 depicts a simple microfluidic complex for purposes of illustrating the heat management techniques of the present invention, and is not intended to depict a microfluidic complex for any particular application. - The channels and chambers of the microfluidic complex are etched in the
bottom surface 112 of theglass substrate 120 using known photolithographic techniques. More specifically, transparent templates or masks containing opaque designs are used to photo-define objects on the surface of the substrate. The patterns on the templates are generated with computer-aided-design programs and can delineate structures with line-widths of less than one micron. Once a template is generated, it can be used almost indefinitely to produce identical replicate structures. Consequently, even extremely complex microfluidic complexes can be reproduced in mass quantities and at low incremental unit cost. - The
lower substrate 127 includes aglass base 130 and anoxide layer 150. Withinoxide layer 150,resistive heaters 140 andelectric leads 160 are formed. The leads 160 connect toterminals 170 which are exposed at the edge of the substrate to permit electrical connection to an external voltage source (not shown) that controls the heaters. More specifically, to activate aheater 140, a voltage is applied across a pair ofterminals 170 to supply current throughleads 160 andheater 140, thereby heating theresistive heater element 140. However, since the same current passes throughleads 160, these leads are also heated. -
Metal heater elements 140 are positioned so that, when the upper and lower substrates are bonded together, the heaters reside directly beneath the fluid chambers of the upper substrate so as to be able to heat the contents of the microchambers. Thesilicon oxide layer 150 prevents theheating elements 140 from directly contacting with fluid in themicrofluidic complex 110. - The
oxide layer 150,heating elements 140, and resistive leads 160 are fabricated using well-known photolithographic techniques, such as those used to etchmicrofluidic complex 110. -
FIG. 2 is a top-down view of the device inFIG. 1 . In this figure,upper substrate 120 is shown atopsubstrate 127 andsilicon oxide layer 150. Eachmicrochamber 125 of the microfluidic complex is directly above acorresponding heater element 140 to allow the heater to raise the temperature of the contents of the chamber. (This relationship is shown more clearly in the cross-sectional end view of the device depicted inFIG. 3 ). - However, as shown in
FIG. 2 , the leads 160 (which supply current to the heaters) pass directly beneathmicrochannel 115. This relationship is more clearly shown in cross-sectional side view of the device depicted inFIG. 4 . -
FIG. 4 clearly shows theleads 160 positioned beneathmicrochannel 115 and separated from thechannel 115 by only a thin layer of oxide. Thus, theleads 160, when carrying current toheater 140, may warm any fluid (or gas or meltable material) in themicrochannel 115, thereby possibly adversely affecting the operation of the microfluidic device. - Referring again to
FIG. 2 , the heater leads 160 also run close to thechannels connecting chambers 125 tochannel 115. Accordingly, when the leads are supplying electric current toheater 140, they may also unintentionally warm the contents of any fluid or wax in the side channels. -
FIGS. 5-7 depict the structure of a first preferred embodiment of the invention which eliminates, or at least substantially reduces, such unwanted heat from the leads. In this structure, theresistive heating elements 540 reside in the oxide layer directly beneathchamber 125, just as they do in the structure shown inFIG. 2 . However, unlike the structure ofFIG. 2 , the electrical leads do NOT reside in theoxide layer 150. Rather, as shown inFIG. 6 , theleads 565 first pass directly through theoxide layer 150 andglass base 130 to the opposite side of the substrate 130 (herein “vertical leads”). Preferably thevertical leads 565 are orthogonal to the plane in whichheater elements 540 reside. - The vertical leads 565 are then connected to
horizontal leads 560, which run along the opposite side ofsubstrate 130 and connect toterminals 570 as shown inFIG. 7 . Also as shown inFIG. 7 , horizontal leads 560 run underchannel 115. However, they are now separated from the channel by thefull oxide layer 150 andbase 130 which act as a thermal isolating layer.Base 130 andoxide 150 should collectively have a sufficiently low thermal conductivity to substantially prevent heat emitted by the leads on the bottom ofsubstrate 130 from adversely affecting the operation of themicrofluidic complex 110. Thus, this configuration substantially reduces the amount of heat transmitted from theleads 560 to themicrofluidic complex 110. - Those skilled in the art will recognize that the above described technique is not limited to microfluidic devices formed from a pair of substrates, such as shown in Fig. Rather, the technique is generally useful in microfluidic devices for reducing unwanted transfer of heat generated by the electric leads. Regardless of how the microfluidic complex is formed, unwanted heat transfer is reduced if the electric leads are routed from the terminals of the heating element through a thermally resistive material, such that the leads are substantially isolated from the microfluidic complex.
- The vertical leads shown in
FIGS. 5 and 6 may be formed by drilling holes throughsubstrate 130 beforeoxide layer 150 andheater 540 are formed. Typically, such holes are 200-500 μm in diameter, but it should be understood that the size of or method of constructing the hole may vary. Preferred means for drilling the holes are related to the desired diameter. For holes 300 μm and greater, mechanical drilling or ultrasonic drilling is preferred, although laser drilling also works. Laser drilling presently works for holes as small as 200 μm in diameter; recent research indicates that laser drilling may also work for holes as small as 50 μm in diameter, or smaller. -
Leads 565 may be run through the holes either by electroplating or by squeezing conductive materials (e.g., pastes) through the holes using screen-printing techniques. Materials for electroplating include aluminum, gold, and nickel, as known in the art. Materials for conductive paste include silver-filled epoxy, although other pastes are known to those skilled in the art to be appropriate. - An alternative method of creating the vertical leads 565 is to form a substrate that comprises a “grid” of vertical leads, such as shown in
FIG. 18 . Referring toFIG. 17 , such a “lead-gridded”substrate 1810 is preferably fabricated by stretching a plurality of wires through a tabular shapedmold 1710, with the wires spaced in the same spacing desired for the intended leads. (Alternatively, the leads can be laid out in a rectangular matrix, for example, and the heater leads run to the nearest pair of vertical leads). Then, a substrate material (such as plastic) is injected into the tube 1710 (or an elongated quadrilateral or another shape appropriate to the method described herein) and surrounds thewires 1720. The result is a cylinder of substratematerial comprising wires 1720 that run parallel to the axis of the tube and that are spaced cross-sectionally as the vertical leads are desired to be spaced in the substrate. SeeFIG. 17 . Then, to obtain a lead-gridded substrate, the remaining steps are to slice the cylinder into across-section 1810 of the desired thickness and polish as necessary. SeeFIG. 18 . Those skilled in the art will recognize the cost efficiency of this method, in that multiple lead-gridded substrates (of uniform or varying thicknesses) can be obtained from a single wired cylinder of the type shown inFIG. 17 . - Referring to
FIGS. 13-15 , unwanted heat transfer from the leads to a microfluidic complex 110 may also be reduced by substantially decreasing the current density in the leads relative to the current density in the heating elements. In the structure shown inFIGS. 13-15 , this is accomplished by providing the leads with a greater thickness than the conductors of theheater element 540. For example, as shown in FIGS. 14,15, theleads 1360 are substantially thicker than the conductor which forms theheating element 540. Increasing the vertical thickness of the lead wires increases the cross-sectional area of the lead wires, thus decreasing the electrical resistance of the wires. This also decreases the current density within the leads and thereby decreases the amount of heat radiated by the leads when a given current is applied. - Referring to
FIG. 16 , heat transfer from the leads to a microfluidic complex 110 may also be reduced by increasing the horizontal thickness of the electric leads 1660 that connectheater elements 540 to a power source. Here, “horizontal” means in a direction parallel to the plane in whichoxide layer 150 lies (refer toFIG. 15 , for example). Theleads 1660 have a length taken along a dimension dl, which is parallel to the plane in whichoxide layer 150 lies.Leads 1660 are thicker thanheater element 540 along a dimension dw, which is parallel to the plane in whichoxide layer 150 lies and orthogonal to dimension dl, of the leads. The preferred configuration is similar to that shown inFIGS. 2-4 . However, the improvement comprised in the embodiment shown inFIG. 16 lies in the increased horizontal thickness ofleads 1660. Increasing the horizontal thickness of the leads increases the cross-sectional area of the lead wires, thus decreasing the electrical resistance of the wires. This in turn decreases the amount of heat radiated by the wires when a given current is applied, thus decreasing the amount of heat transferred from the wires tomicrofluidic complex 110. - An advantage of increasing the horizontal thickness instead of the vertical thickness is that there is less likely to be a need to increase the thickness of the
oxide layer 150. On the other hand, an advantage of increasing the vertical thickness instead of the horizontal thickness is that a greater number of leads can be used on the substrate without interfering with each other. - In a still further embodiment, the thickness of the leads is increased in both the horizontal and vertical directions. Those skilled in the art will recognize that the leads can be modified in a variety of ways without departing from the scope of the invention, as long as it results in a substantial decrease in the current density within the leads (relative to the current density in the heating elements) to thereby reduce the amount of heat transferred from the leads to the microfluidic complex to an acceptable level (i.e., a level that does not significantly interfere with the operation of the microfluidic complex).
- Other embodiments comprise combinations of the elements above that will be clear to those skilled in the art. For example, the vertical feed through, shown in
FIGS. 5-7 , can be combined with the thickened leads, (FIGS. 13-16 ), so that the leads 565 (see, e.g.,FIG. 7 ) that are run “vertically” through thesubstrate 130 are increased in thickness, to further reduce heat emitted by theleads 565 and potentially transferred to themicrofluidic complex 110. Similarly, the leads 560 (again, seeFIG. 7 ) that run along the lower side ofsubstrate 130 can also be increased in thickness to reduce heat emitted by theleads 560 that could be transmitted to the microfluidic complex 110, although preferably thesubstrate 130 is comprised of material with a thermal conductivity low enough to make such a modification unnecessary. - The amount of heat in a microfluidic complex may also be controlled using one or more Peltier devices. See
FIGS. 8-12 . Such devices can be made to act as heat pumps, removing unwanted heat from a microfluidic complex or component thereof. Peltier devices are well-known (see U.S. Pat. No. 5,714,701, to Chi et al., for example). Peltier discovered the effect that bears his name in 1834. Modem Peltier devices (also known as thermoelectric cooling devices) are typically composed of segments of heavily-doped semiconductors (often bismuth telluride) that are connected electrically in series and thermally in parallel between the heated and cooled surfaces of the device. Such devices are available commercially, for example, from MELCOR, 1040 Spruce Street, Trenton, N.J. 08648; see also http://www.melcor.com. - In this second preferred embodiment, at least one
Peltier device 810 is attached to thesubstrate 130, although in an alternate embodiment at least one Peltier device 910 (seeFIG. 9 ) is attached to theupper substrate 120 of a preferred microfluidic device. This “upper”Peltier device 910 can be in addition or an alternative to any “lower”Peltier devices 810 attached to thesubstrate 130. Preferred Peltier devices are battery-operated, and are attached tosubstrate 130 orsubstrate 120 using a heat-transfer paste, to improve heat conduction. In this embodiment, a Peltier device is used to cool an entire microfluidic chip. As discussed below, Peltier devices are used in other embodiments to cool selected areas of a chip, sometimes cooling different areas at different times, depending on the preferred operation of a microfluidic complex in the chip. - Peltier devices are preferably used to remove heat primarily from selected areas of a microfluidic complex. For example, unnecessary power consumption would result if a Peltier device was cooling the entire substrate at the same time that a heater element was attempting to heat a selected chamber in the substrate. By using a plurality of Peltier devices, controlled electronically, heat can be removed from selected areas of a microfluidic complex while allowing other areas to be heated with a minimum of consumed power.
FIG. 10 shows twoPeltier devices 1010 attached to the bottom ofsubstrate 130 so as to be capable of cooling selected areas (microchambers 125) of a microfluidic complex insubstrate 120. The depicted configuration is, of course, merely exemplary—any operable configuration of multiple Peltier devices, where the Peltier devices are of any compatible collection of shapes, would also work in this embodiment. Further, although the depicted configuration is for a chip with heater leads as inFIGS. 5-7 , a multiple-Peltier-device configuration can also be used on a microfluidic device such as that depicted inFIGS. 2-4 . MultiplePeltier devices 910 can be similarly configured on thetop substrate 120 of a microfluidic device. Peltier devices can be used to cool an entire microfluidic chip, an entire microfluidic complex, or selected portions (channels, chambers, etc.) thereof, and different Peltier devices can be used at different times, depending on desired functionality of the microfluidic complex. -
FIGS. 11 and 12 depict cross-sectional views of the device inFIG. 10 . Asilicon oxide layer 1150 covers heater leads 560. A heat-transfer paste lies betweensilicon oxide layer 1150 andPeltier devices 1010. - While the operations described above have been for simple designs, the present invention contemplates more complicated devices involving the introduction of multiple samples and the movement of multiple microdroplets (including simultaneous movement of separate and discrete droplets), as well as multiple microchannels and microchambers, and potentially including meltable materials. Furthermore, as discussed above, those skilled in the art will recognize that the subject invention is not limited to microfluidic devices comprised of one glass substrate bound to another, or to microfluidic complexes formed by etching or otherwise forming chambers and channels into the bottom surface of an upper substrate that is then bonded to a lower substrate, or even to microfluidic devices formed by bonding one substrate to another. The present invention will be recognized by those skilled in the art as applying to any microfluidic device that comprises a microfluidic complex having a heating region.
- Moreover, although much of the above description depicts, for simplicity of explanation, two leads running from each heater element, it is possible to share leads among heater elements so that, for example, two heater elements can be served by three leads (e.g., with the shared lead serving as a common ground).
