Nitric oxide can be electrocatalytically reduced at electrodes modified with electropolymerized films of [Cr(v-tpy)2]3+. Upon further modification with a thin film of Nafion (to prevent interferences from anions, especially nitrite), these electrodes can be employed as NO sensors in solution with submicromolar detection limits and fast response. We have carried out preliminary studies of cellular NO release from Rhodobacter sphaeroides bacterial cells with excellent results.
一氧化氮可以在修饰有[Cr(v - tpy)₂]³⁺电聚合膜的电极上进行电催化还原。在用Nafion薄膜进一步修饰（以防止阴离子尤其是亚硝酸盐的干扰）后，这些电极可用作溶液中的NO传感器，检测限可达亚微摩尔级，且响应迅速。我们已经对球形红细菌细胞释放细胞内一氧化氮进行了初步研究，结果非常出色。
