硫离子荧光探针的研究进展

Advances in Sulfur Ion Fluorescence Probes

硫化物在自然界中广泛存在,但它具有一定毒性,因此,研究出一种方便,快捷的检测方法显得尤为重要。由于荧光探针具有操作简单、选择性高、响应快速等优点,它的出现引起了科学家的广泛关注。本文综述了最近几年硫离子荧光探针的研究进展,并介绍了荧光探针的分类、作用机理,依据反应机理的不同将硫离子荧光探针分为两类,即反应型荧光探针和置换型荧光探针。本文对这两类荧光探针的设计原理和检测结果进行了详细的阐述,并在公共安全领域方面进行了展望。

Sulfide is widely used in nature,but it has certain toxicity. Therefore,it is very important to study a convenient and fast detection method. Because the fluorescent probe has the advantages of simple operation,high selectivity and rapid response,its emergence has attracted wide attention of scientists. Sulfur ions in recent years was reviewed in this paper the research progress of fluorescent probes,and introduces the classification,action mechanism of fluorescent probes,on the basis of reaction mechanism of different sulfur ion fluorescent probe can be divided into two categories,namely the reaction type fluorescent probes and the displacement type fluorescent probe. In this paper,the design principles and test results of these two kinds of fluorescent probes are described in detail,and the prospect of the field of public safety is also discussed.
