Summary:This paper reports a novel mediator for the oxidation of beta -nicotinamide adenine dinucleotide (NAD/NADH), an electropolymeric film (pAPRu) of [Ru(NH(2)-phen)(3)](2-). A pAPRu-modified electrode was prepared via electropoly-merization and exhibited catalytic activity toward the electrochemical oxidation of NADH due to the imine moieties of pAPRu. The electrochemical oxidation of ethanol was observed using an alcohol dehydrogenase (ADH)-im-mobilized electrode. A compartmentless ethanol/O(2) biofuel cell composed of an ADH anode and a bilirubin oxidase cathode was constructed. The maximum current density and the maximum power density of the biofuel cell were 190 mu Acm(-2) and 31 mu Wcm(-2) (at 0.29 V), respectively.
