Abstract:

Electron transfer mediation to an anode, whose potential is judiciously controlled, provides the conceptual basis for the development of novel chronoamperometric biosensors. The mediators are appropriately selected redox couples (Ox/Red) which are amenable to recycling in the following type of enzyme E catalyzed reaction sequence

$\begin{gathered} {\text{Substrate + Ox}}{}^{\text{E}} \to {\text{ Product + Red }} \hfill \\ {\text{Red }} \to {\text{ Ox + }}ne^ - {\text{ }} \hfill \\ \end{gathered}$

Keywords:	Alcohol oxidase biosensors chronoamperometry electron transfer mediation enzymatic redox mechanisms glusose oxidase pseudo-oxidase substrate/co-substrate selectivity
