染色体和荧光反应物是指示剂染料，允许对电中性分析物进行光学检测。与络合剂如杯芳烃、环糊精或环番不同，反应物与分析物分子形成可逆共价键。这种化学反应会引起吸光度或荧光的强烈变化。本文介绍了胺类、醇类、醛类、酯类、二氧化碳和二氧化硫等分析物的反应物。讨论了提高反应物灵敏度的方法以及相应光学传感器的使用寿命和保存寿命。
Chromo- and fluororeactands are indicator dyes that allow the optical detection of electrically neutral analytes. Unlike complexing agents such as calixarenes, cyclodextrines or cyclophanes, reactands form a reversible covalent bond with the analyte molecule. This chemical reaction causes strong changes in absorbance or fluorescence. In this article reactands for analytes such as amines, alcohols, aldehydes, saccharides, carbon dioxide and sulfur dioxide are presented. Methods to enhance the sensitivity of the reactands as well as the operational and shelf lives of the corresponding optical sensors are discussed.
