| Abstract: | Hg2+not only results in environmental pollution,but also causes a variety of diseases and is harmful to human health.Therefore,it is essential to achieve the rapid and sensitive detection of Hg2+.Traditional Hg2+detection methods have some limitations in applications.Recently,Hg2+biosensors based on T-Hg2+-T structure have been widely studied and applied because of their high specificity and stability.This paper briefly introduced the concept and characteristics of T-Hg2+-T structure and reviewed the research progress of fluorescent,colorimetric and electrochemical Hg2+biosensors based on T-Hg2+-T structure.The future prospect of such kind of biosensor was also discussed. |
