荧光探针检测2,4,6-三硝基苯酚研究进展

Recent Progress in Research of Fluorescent Probes for Detection of 2, 4, 6-Trinitrophenol

在当前恐怖主义和爆炸袭击高发的国际环境下,安检和边防对于爆炸物的检测需求越来越高,爆炸物的快速灵敏检测成为关乎国家安全和环境保护等方面的研究热点。2,4,6-三硝基苯酚(TNP)由于使用率高,爆炸威力强而引起专家学者的广泛关注。在众多的TNP检测技术中,荧光探针因其快速、灵敏、成本低廉、操作简便等优势倍受青睐,是一种理想的现场检测工具。本文总结了近年来用于TNP检测的各类荧光探针,并根据其分子的组成与特性,将其分为纳米材料型、有机高分子型和有机小分子型等三类,系统地介绍了相应探针在TNP检测中的研究进展,并展望了其未来发展趋势。

Under the currently international situation of high incidence of terrorist attacks and explosions,there is an evergrowing demand for explosive detection.2,4,6-Trinitrophenol(TNP),also named as picric acid(PA),is one of the common explosive components and strong exploding power.Increasing attention has in recent years been attracted to the highly selective,sensitive and rapid detection of TNP due to the concerns of public safety and environmental contamination.Among the methods of TNP detection,fluorescent probes have been extensively investigated because of their fast response,high sensitivity,low cost and ease of operation.In this review,fluorescent probes used for rapid TNP detection are summarized and classified into three categories according to their compositions and properties:the nanomaterial-based,polymer-based and small molecule-based.Together,the progress is concluded and prospected in such research area.
