Аннотация:The electrochemical regeneration of nicotinamide adenine dinucleotide (NAD(+)/NADH) has been one of the central subjects of bioelectrochemistry during past three decades. We report on the unique chemical electrocatalyst for NAD(+)/NADH regeneration based on electropolymerized Neutral Red. Using poly(Neutral Red) modified electrodes, the reversible polarographic waves of nicotinamide adenine dinucleotide reduction-oxidation and the equilibrium (NAD(+)/NADH) potential were observed. This was impossible using all known catalytic and mediator systems. The unique poly(Neutral Red) based electrocatalyst allowed us to determine the standard (NAD(+)/NADH) potential more precisely (E' congruent to 0.59 V SCE, pH 6.0). (C) 2003 Published by Elsevier B.V.
