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.
