Nitric oxide (NO) was implicated in a wide range of biol. processes including cellular signaling, coronary artery dilation, immune system response, and neurotransmission. With this in mind, the development of direct, sensitive, and selective sensing schemes for NO has attracted great interest in recent years. The development of a selective, ppm level, gas-phase NO detection system based on chemoresistive changes in a cobalt-contg. metallopolymer film device is discussed. These films are easily prepd. and elec. interfaced, and showed detection limits of NOx <1 ppm. [on SciFinder(R)]
