Abstract
Electrochemical determination of the presence, and optionally concentration of an analyte utilizes an electrode having immobilized thereon one member of a recognition pair, the recognition pair consisting of said analyte. In the presence of the analyte medium pair complexes, which are complexes between the analyte and the immobilized member are formed. The electrode forms part of an electrochemical system which includes also redox molecules comprising at least one first redox molecule and at least one second redox molecule, the former transferring electrons between the electrode and the latter. Upon formation of a pair complex the electron transfer is inhibited and the change in the electrical response then indicates the presence of said analyte in the medium.
