近年来,电位型传感器或所谓的离子选择电极领域的研究工作大多集中于新型敏感材料的探索方面。除了探索非玻璃类型的pH敏感膜材料外,还进行了多种阴离子敏感材料的研究。不同的新化学概念,特别是超分子化学的应用,为新型敏感材料的探索提供了实验研究的理论基础。本文报道了具有广泛pH响应范围的基于叔胺—重氮化合物载体的非玻璃型pH传感器以及具有明显反Hofmeister顺序特性的基于金属卟啉化合物和金属酞菁化合物的硝酸根、水杨酸根、硫氰根及磷酸根传感器。本文还报道了基于微电子技术的多种化学与生物传感器,特别是作者近期研制的以微机械加工技术制作的做腔型化学和生物传感器,已显示了优异的性能。
In recent years, most of the research in the field of potential sensors or so-called ion-selective electrodes has focused on the exploration of new and sensitive materials. In addition to exploring non-glass-type pH-sensitive membrane materials, a number of anion-sensitive materials have also been studied. Different concepts of new chemistry, especially the application of supramolecular chemistry, provide the theoretical basis for the exploration of new and sensitive materials. A non-glass pH sensor based on a tertiary amine-diazo compound carrier with a wide range of pH response and nitrate, salicylate, and sulfur based metalloporphyrin compounds and metal phthalocyanine compounds with significant anti-Hofmeister sequence properties is reported Cyanide and phosphate sensors. This paper also reports on a variety of chemical and biological sensors based on microelectronic technology, especially the recently developed micro-machined cavity-forming chemistries and biosensors that have demonstrated excellent performance.
