A method for making a sensing element for use in a sensor or biosensor that amperometrically measures the concentration of an analyte in a liquid, includes the following sequential steps: a) obtaining an electrode; b) immersing the electrode in a solution of monomer that is capable of being electropolymerized into an electrically insulating polymer; c) flowing an electric current from a cathode through the solution to the electrode at a voltage and amperage sufficient to cause the monomer to polymerize on the surface of the electrode, thereby yielding an electrode coated with an adherent layer of electrically insulating polymer; and e) impregnating the polymeric coating on the surface with a sensing agent that is capable, when contacted by a specific analyte in a chemical or biological liquid, of generating an electroactive molecule that can be detected amperometrically.

A method for making a sensing element for use in a sensor or biosensor that amperometrically measures concentration of an analyte in a liquid, said method comprising the following sequential steps: a) obtaining an electrode; b) immersing said electrode in a solution of monomer; c) flowing an electric current from a cathode through said solution to said electrode at a voltage and amperage sufficient to cause the monomer to polymerize on the surface of the electrode, thereby yielding an electrode coated with an adherent layer of electrically non-conducting polymer; d) immobilizing a sensing agent on a surface of the polymeric coating, whereby the sensing agent has a property of selectively interacting directly with the analyte which is then directly sensed by the electrode.
