Electrocatalytic activity of 6,7-dihydroxy-3-methyl-9-thia-4,4a-diazafluoren-2-one/multi-wall carbon nanotubes immobilized on carbon paste electrode for NADH oxidation: Application to the trace determination of NADH

A 6,7-dihydroxy-3-methyl-9-thia-4,4a-diazafluoren-2-one/multi-wall carbon nanotubes (DDF/MWCNT) film-modified carbon paste electrode (CPE) has been fabricated. The electrochemical oxidation of the behavior of reduced nicotinamide adenine dinucleotide (NADH) has been studied at DDF/MWCNT film-modified CPE by electrochemical methods. The DDF/MWCNT film-modified CPE showed a pair of well-defined, quasi-reversible cyclic voltammogram (CV) which...
