摘要:金属离子对自然环境和生物体的生长发育具有重要的影响,因此对环境中及生物体内的金属高子的识别
和检测正日益受到人们广泛的关注。在不同的分析方法中,荧光分析法具有灵敏度高、选择性好和实时原位检
测等优点,是实现环境中和生物体内金属离子识别和检测的良好工具。本文综述了近5年来香豆素类荧光传感
器对一些重金属离子(Hg2+、Pb、Cd、NP、Ag)和一些具有重要生物学意义的过渡金属离子(Cu2、Zn2
Fe)的识別与检测及其应用进展情况,着重介绍了传感器分子的设计合成、识别机理、传感特性及其在环境分
析和生物检测中的应用。随着金属离子检测要求的提高,未来香豆素类荧光传感器的设计将向着灵敏度更高、
选择性更好、抗千扰性能更强的方向发展。此外,香豆素类传感器在生物检浏中的应用研究有望得到进一步
发展

Abstract: Metal ions have a significant impact on the environment and the growth and development of
organism, therefore, the recognition and detection of metal ions in the environment and organism is
gaining widespread attention. Among different analytical methods, fluorescence analysis has the
advantages of high sensitivity, good selectivity, real-time and in situ detection, etc, which is a good
tool to achieve the recognition and detection of metal ions in the environment and organism. This paper
is aimed to review the coumarin-based fluorescent sensors for the recognition and detection of heavy
metal ions(Hg3+、Pb2、Ct2、N2、Ag), biologically important transition metal ions(cue2、Zn2
Fe)and their applications in recent five years, focusing on the design and synthesis of sensors
recognition mechanism, sensing characteristics and applications. With the higher requirement for metal
ions detection, the design of coumarin-based fluorescent sensors will be developed for better
performance with higher sensitivity, selectivity and stronger anti-interference in the future. In addition
applications of coumarin-based fluorescent sensors in biological detection are expected to be further
evelope
