Electrocatalytic Oxidation of NADH by Poly Toluidine Blue Multi Walled Carbon Nanotubes Modified Glassy Carbon Electrode

Popis výsledku v původním jazyce

In this study, a stable electroactive thin film of poly Toluidine blue (PTB) was fabricated at the surface of multi-walled carbon nanotube (MWCNT) modified glassy carbon electrode (GCE) by recording successive cyclic voltammograms of 0.25 mM Toluidine blue (TB) in a Britton Robinson bufer solution (pH 9.0) containing 0.1 M NaNO3 at the potential range from -0.5 to +1.0 V vs. Ag/AgCl. This PTB/MWCNT/GCE exhibited a good electrocatalytic effect towards the oxidation of reduced ß-Nicotinamide Adenine Dinucleotide (NADH) in phosphate buffer solution (PBS) pH 7.0 containing 0.1 M KCl at a reduced overpotential as well as an increased peak current compared with those at a bare electrode. The currents obtained from the amperometric measurements at optimum conditions (supporting electrolyte: pH 7.0 PBS containing 0.1 M KCl and constant applied potential: +150 mV vs. Ag/AgCl) were linearly correlated with the NADH concentration. The calibration curve was obtained for NADH concentrations in a ra
