The CNT/GC electrode showed excellent electrocatalytic activity toward dopamine electrochemical reaction without introducing any electrochemically active group into CNT film or activating the electrode electrochemically. DA undergoes ideal reversible electrochemical reaction on CNT/GC electrode at low scan rate ( less than or equal to 20 mV/s) with an excellent reproducibility and stability. The CNT/GC electrode might be used in biosensors because the highly ordered CNT may present a steric effect on more efficient redox reactions of biomolecules.展开更多

The electrode exhibits potent electrocatalysis for NADH oxidation in PBS (pH 6.8) with a diminution of the overpotential of more than 600 mV. The anodic peak current increases linearly with NADH concentration from 2?0-5 mol/L to 1?0-3 mol/L with the detection limit of about 5?0-7 mol/L.展开更多
