Abstract: This report describes the development of a simple, easy to fabricate, sensitive, and stable nitric oxide sensor. The sensor is based on the N ′, N ″-(1, 3-proanediyliene)bis(1, 2-benzene diamino-N, N ′, N ″, N′″-nickel(Ni(Ⅱ)L) mediator is electropolymerized on a platinum, Nafion-modified microelectrode(diameter 15 μm). The detection of NOis based on the Ni(Ⅱ)Lcatalysis of NOoxidation at an anodic potential of +0.74 V. The electrocatalytic oxidation mechanism is also discussed. The Ni(Ⅱ)L modified microelectrode was used to monitor NOin human blood, the results suggest that the sensor can detect NOin vitro .

Key words: Nitric oxide, NO detection, Nafion-polyNi(Ⅱ)L modified microelectrode
