| 摘 要： | Nicotinamide adenine dinucleotide (NAD ) and its reduced form NADH used as coenzymes by over 300 dehydrogenases have been the subjects of numerous studies. Direct oxidation of NADH at a bare electrode only proceeds at high overpotentials, which finally le…

| Abstract: | A novel approach based on self-assembled colloidal gold and Nafion matrixes and Co complex mediator to construct Co(bpy)33 /nano-Au/Co(bpy)33 /nafion/GC electrode, on which formed stable redox-active films. This electrode can decrease the overpotential about 330 mV for the oxidation of NADH with high stability, wide linear range and low detection limit. |
