Patent ID: 7879534

Claim:
A method of manufacturing a detection device comprising: providing a substrate having a layer of electrically conductive material between a layer of photosensitive material and a base layer, subjecting the substrate to a photolithography treatment to produce an electrical conductor comprising conductive fingers with spaces between them; and attaching biological probes to the conductive fingers under conditions effective to form a gap between the biological probes on the spaced apart conductive fingers, whereby a target molecule, if present in a sample, can bind to a pair of the biological probes on the spaced apart conductive fingers to bridge the gap between the biological probes, allowing detection of the target molecule; wherein said substrate further comprises: a first layer of electrical insulator material between the base layer and the layer of electrically conductive material; and a coating of adhesive material between the layer of electrical insulator material and the layer of electrically conductive material.
