【摘要】 环境中广泛存在着众多的天然和人工合成的手性对映体,手性对映体主导着自然界的奇妙和生命的奥秘.在环境分析中需要探索手性对映体污染物的作用和变迁,自然环境中的手性环境能自然开启手性识别和激活手性,而人为介入的手性识别需要高灵敏度和高选择性相结合的分析手段.许多高灵敏度且简便易行的光谱分析方法,借助有机染料、纳米粒子或量子点等手性选择性试剂,或合成设计某些光散射探针试剂可形成高效的选择性手段.筛查手性选择性试剂或手性光散射探针试剂与荧光、散射相结合的手性识别则是一项创新工作.发展不经分离而同时测定手性污染物的新分析方法是一项有意义的探索.更多还原

【Abstract】 Chiral enantiomers dominate the wonders of nature and the mysteries of life. Numerous natural and synthetic chiral enantiomers exist widely in the environment, which plays a magnificent variety of roles. Chiral recognition and analysis are used to measure, characterize and explore the functions and changes of the chiral enantiomers in environmental analysis. In Natural environment, chiral environment can naturally launch into chiral recognition and chiral activation, while chiral recognition in human intervention requires the analytical tools to combine high sensitivity with high selectivity. Many spectral analysis methods with high sensitivity and simplicity draw support from chiral selective reagents such as organic dyes, nanoparticles, quantum dots, or synthesize and design certain light scattering probe reagents to form high effective and selective means. Chiral recognition of screening combines chiral selective reagents or chiral light scattering probe reagents with fluorescence, and scattering is an innovative work. It is a valuable exploration to develop molecular spectroscopy analysis methods of chiral recognition as the leading of chiral selective reagents or chiral light scattering probe reagents, and it further expands and then establishes a new analysis method of simultaneous determination without separation of chiral enantiomers.更多还原
