摘　　要：A novel approach based on self-assembled colloidal gold and Nation matrixes and Co complex mediator to construct Co（bpy）3^3＋/nano-Au/Co（bpy）3^3＋/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.A novel approach based on self-assembled colloidal gold and Nation matrixes and Co complex mediator to construct Co（bpy）3^3＋/nano-Au/Co（bpy）3^3＋/nafion/GC electrode, on which formed stable redox-active films.
