Nitric oxide (NO) is a highly reactive toxic gas that forms as an intermediate compound during the oxidation of ammonia and is used for the manufacture of hydroxylamine in the chemical industry. Moreover, NO is a signaling molecule in many physiological and pathological processes in mammals, as well as a biomarker indicating the course of inflammatory processes in the respiratory tract. For this reason, the detection of NO both in the gas phase and in the aqueous media is an important task. This review analyzes the state of research over the past ten years in the field of applications of phthalocyanines, porphyrins and their hybrid materials as active layers of chemical sensors for the detection of NO, with a primary focus on chemiresistive and electrochemical ones. The first part of the review is devoted to the study of phthalocyanines and porphyrins, as well as their hybrids for the NO detection in aqueous solutions and biological media. The second part presents an analysis of works describing the latest achievements in the field of studied materials as active layers of sensors for the determination of gaseous NO. It is expected that this review will further increase the interest of researchers who are engaged in the current level of evaluation and selection of modern materials for use in the chemical sensing of nitric oxide.
一氧化氮(NO)是一种高度反应性的有毒气体,它在氨氧化过程中形成中间体化合物,用于化学工业中羟胺的制造。此外,NO 是哺乳动物许多生理和病理过程中的信号分子,也是指示呼吸道炎症过程进程的生物标志物。因此,检测气相和水相中的 NO 是一项重要任务。本综述分析了过去十年中酞菁、卟啉及其杂化材料作为化学传感器检测 NO 的活性层的研究现状,重点研究了化学电阻型和电化学型传感器。综述的第一部分致力于研究用于检测水溶液和生物介质中 NO 的酞菁和卟啉及其杂化物。第二部分分析了描述作为用于测定气态 NO 的传感器的活性层的研究材料的最新成果的工作。预计本综述将进一步提高从事当前评估和选择现代材料用于化学感测一氧化氮的研究人员的兴趣。
