✦ Synopsis
We report here a novel enzyme electrode obtained by electrochemically copolymerization of a redox enzyme with an oligomeric organic redox mediator on the surface of a glassy carbon electrode. This electrode serves as an efficient catalyst for the regeneration of the cofactor in enzymatic syntheses requiting NADH. The reaction shows a relatively short induction period and the rate of product formation is higher than for similar electrodes upon which the enzyme and redox mediator are physically trapped under a Nafion membrane.
