Benzimidazole modified silver electrode which was prepared by a surface complexinduced reaction was not only stable,long-lived, but also could be used for the electrochemical reduction of NAD+. The anodic and cathodic peaks of the modified electrode were at 0. 25V and 0. 10 V respectively.After addition of NAD+ to the test solution, the cathodic peak ofthe reductive process of NAD+ could be observed at about -0. 03 V and the peak currentwas dependent directly on the NAD+ concentration.
