Claim:
1. An amperometric immuno-sensing system embodied in the form of an electrochemical cell system, the system comprising a working electrode, a reference electrode, and a counter electrode connected as a three-electrode cell, an enzyme-labeled antigen or an enzyme-labeled antibody, and an additional electrode, wherein the additional electrode is operatively connected to an external voltage source, wherein the enzyme-labeled antigen or the enzyme-labeled antibody is immobilized on the working electrode; and wherein the additional electrode is configured to apply an external voltage from the external voltage source between the additional electrode and the working electrode to induce an electric field, at least a portion of an interface between the enzyme-labeled antigen or the enzyme-labeled antibody and the working electrode being permeated by the electric field.
