An excellent electrocatalysis of poly(phenosafranine)-modified electrode for oxidation of reduced β-nicotinamide adenine dinucleotide

Abstract

A poly(phenosafranine)-modified electrode, which can be prepared by a potential-sweep oxidative electrolysis of the corresponding monomer in both aqueous and acetonitrile media, shows excellent electrocatalytic activity for NADH oxidation in phosphate buffer solutions (pH 7), with an activation overpotential which is more than 1 V lower than that of the bare electrode.
