传统的分析物特异性合成受体或传感器已经基于超分子相互作用(例如,氢键、静电、弱配位键)。不幸的是,这种方法往往受到限制。因此,化学传感器社区内越来越多的注意力转向分析物特异性分子指示剂的使用,其中底物触发的反应用于发出给定分析物存在的信号。本教程回顾强调了最近的反应为基础的指标体系,已被用来检测选定的阴离子,阳离子,活性氧和中性基板。
Traditional analyte-specific synthetic receptors or sensors have been developed on the basis of supramolecular interactions (e.g., hydrogen bonding, electrostatics, weak coordinative bonds). Unfortunately, this approach is often subject to limitations. As a result, increasing attention within the chemical sensor community is turning to the use of analyte-specific molecular indicators, wherein substrate-triggered reactions are used to signal the presence of a given analyte. This tutorial review highlights recent reaction-based indicator systems that have been used to detect selected anions, cations, reactive oxygen species, and neutral substrates.
