The invention relates to a method for detecting polynucleotides on a substrate, whereby the substrate contains a multitude of separate detection regions each accommodating different polynucleotides. The polynucleotides in the detection regions exist, contrary to known DNA chip test formats, in a form...http://www.google.com/patents/US7553620?utm_source=gb-gplus-sharePatent US7553620 - Method for determining polynucleotides in a sample without attaching these to a support, and using detection probes
