Poly-phenothiazine derivative-modified glassy carbon electrode for NADH electrocatalytic oxidation
(2009) In Electrochimica Acta 54(11). p.3124-3128- Abstract
- Electropolymerization of a new phenothiazine derivative (bis-phenothiazin-3-yl methane; BPhM) on glassy carbon (GC) electrode generates a conducting film of poly-BPhM. in stable contact with the electrode surface. The heterogeneous electron-transfer process corresponding to the modified electrode is characterized by a high rate constant (50.4 s(-1), pH 7). The CC/poly-BPhM electrode shows excellent electrocatalytic activity toward NADH oxidation. The rate constant for catalytic NADH oxidation, estimated from rotating disk electrode (RDE) measurements and extrapolated to zero concentration of NADH, was found to be 9.4 x 10(4) M-1 s(-1) (pH 7). The amperometric detection of NADH, at +200 mV vs. SCE, is described by the following... (More)

The amperometric detection of NADH, at +200 mV vs. SCE, is described by the following electroanalytical parameters: a sensitivity of 1.82 mA M-1, a detection limit of 2 mu M and a linear domain up to 0.1 mM NADH.
