摘要：

A novel nanocomposite of quinone-amine polymer and multiwalled carbon nanotubes was synthesized from iodate-oxidation/Michael addition reaction of 1,2-dihydroxybenzene with o-phenylenediamine, which was characterized by TEM, FTIR and UV-vis spectra. The nanocomposite modified Au electrode with well-defined quinone redox peaks effectively mediated the oxidation of NADH in pH 7.0 phosphate buffer, with an overpotential decrease by ca. 470 mV (vs. bare An), a limit of detection of 6.4 nmol L-1 and good antiinterferent ability.
