Claim Text:
1. A sensor fabrication method comprising the steps of: a) polymerizing a layer of polysiloxane onto a substrate such that it sufficiently adheres thereto, wherein the substrate is selected from a group consisting of electrodes, diodes, field effect transistors, insulated gate field effect transistors, and metal oxide semiconductor field effect transistor; and b) adsorbing heptapeptide ligand selector molecules onto the layer of polysiloxane, wherein the steps of polymerizing and adsorbing occur concurrently and absent from an electrical voltage or current applied to the substrate and comprise: immersing the substrate in a solution or a suspension including polysiloxane-forming monomers and selector molecules, both polysiloxane-forming monomers and selector molecules being dispersed in the bulk of the solution or suspension, and wherein the polymerizing step and the adsorbing step hold heptapeptide ligand selector molecules onto the substrate by using hydrophobic silanol groups of the polysiloxane layer.
