Abstract
This paper describes, for the first time, the development of a simple and highly sensitive chemical sensor based on a new electroactive material, electrogenerated in situ from xanthurenic acid on an electrode modified with MWCNT. The modified electrode shows efficient electrocatalytic oxidation activity towards NADH at an applied potential of 0.1 V vs. Ag/AgCl. The kinetic constant, kkin, for the electrocatalytic oxidation of NADH, evaluated by chronoamperometry and voltammetry using RDE, provided values close to 105 mol−1 L s−1.
