Abstract
A kinetic model is presented for the operation of an amperometric enzy me electrode in which a single electroactive enzyme oxidizes both the initial substrate and the primary reaction product. Two examples of th is type of electrode have been investigated: the hypoxanthine + xanthi ne and choline + betaine aldehyde systems, which utilize the enzymes x anthine oxidase and choline oxidase respectively. The conducting organ ic salt tetrathiafulvalinium tetracyanoquinodimethanide is used as the electrode material in both sensors.
