Progress on Research and Application of Heavy Metal Ion Fluorescent Probes

荧光探针因具有高灵敏度、高选择性、使用便捷、成本低廉、样品不需要预处理等优点而备受关注,如今已成为一种重要的荧光传感分析方法。对荧光探针的识别机理、各种荧光探针分子在离子检测方面的应用作了简要介绍。介绍了卟啉类、罗丹明类、萘酰亚胺类、喹啉类、香豆素类和荧光纳米材料类等不同类型的荧光探针在重金属离子检测领域的研究与应用情况;阐述了重金属离子荧光探针的研究方向和前景,对其未来的发展趋势作了进一步的展望。

Fluorescent probes with advantages of high sensitivity, high selectivity, easivess to use, low cost, and no sample pretreatment have attracted much attention, and it has now become an important fluorescence sensing analysis method. The recognition mechanism of fluorescent probe and the application of various fluorescent probe molecules in ion detection were briefly introduced. The use of different types of fluorescent probes such as porphyrin, rhodamine, naphthalene acyl imine, quinoline, coumarin, fluores cent nano-materials and so on in the detection of heavy metal ions was emplhasised. Meanwhile, the pros pects and the future development trend of heavy metal ion fluorescence probes was discussed.
