A novel electrochemical sensor for the simultaneous determination of glutathione (GSH) and
nicotinamide adenine dinucleotide (NADH) is described. The sensor is based on a carbon
paste electrode (CPE) modified with benzamide derivative and multiwall carbon nanotubes.
This mixture makes a modified electrode that is sensitive for the electrochemical detection of
these compounds. Under optimum conditions and at pH 7.0, oxidation of GSH occurs at a
potential of about 330mV less positive than that at an unmodified CPE. The voltammetric ...
