Abstract

As a persistent bioaccumulative toxin, mercury ion (Hg²⁺) presents grave environmental and public health risks due to their extreme toxicity and neurological damage potential. The advancement of reliable Hg²⁺ detection methodologies become imperative for safeguarding ecological security and food supply chains. In recent years, different signal output modes have been explored for Hg²⁺ detection. This review systematically summarizes the latest detection techniques and strategies for Hg²⁺ based on electrochemical signal, fluorescence signal, SERS signal and colorimetric signal. Innovation designs of functional materials, small molecules, nanoprobes and strategies for Hg²⁺ detection have been introduced and their detection performances including sensitivity, selectivity and portability are compared with each other. The comparison results show that some methods can achieve ultrasensitive detection of Hg²⁺ at fM level. In addition, the challenges and perspective for Hg²⁺ detection have been discussed. The review is expected to provide insights for the development of highly sensitive and portable detection tools for Hg²⁺, and promote the transformation of Hg²⁺ detection technology from the laboratory to industrialization.

汞离子检测新进展（2019-2025）

汞离子（Hg2+）作为一种持久性生物蓄积性毒素，由于其极高的毒性和潜在的神经损伤，给环境和公众健康带来了严重的风险。发展可靠的Hg2+检测方法对于保障生态安全和食品供应链至关重要。近年来，人们探索了不同的Hg2+检测信号输出模式。本文系统地综述了基于电化学信号、荧光信号、SERS信号和比色信号的最新Hg2+检测技术和策略。介绍了功能材料、小分子、纳米探针和Hg2+检测策略的创新设计，并对其灵敏度、选择性和可移植性等检测性能进行了比较。比较结果表明，一些方法可以在fM水平上实现Hg2+的超灵敏检测。此外，还讨论了Hg2+检测面临的挑战和前景。希望能为高灵敏度、便携式Hg2+检测工具的开发提供参考，促进Hg2+检测技术从实验室向产业化的转变。

期刊介绍： Critical Reviews in Analytical Chemistry continues to be a dependable resource for both the expert and the student by providing in-depth, scholarly, insightful reviews of important topics within the discipline of analytical chemistry and related measurement sciences. The journal exclusively publishes review articles that illuminate the underlying science, that evaluate the field''s status by putting recent developments into proper perspective and context, and that speculate on possible future developments. A limited number of articles are of a "tutorial" format written by experts for scientists seeking introduction or clarification in a new area. This journal serves as a forum for linking various underlying components in broad and interdisciplinary means, while maintaining balance between applied and fundamental research. Topics we are interested in receiving reviews on are the following: · chemical analysis; · instrumentation; · chemometrics; · analytical biochemistry; · medicinal analysis; · forensics; · environmental sciences; · applied physics; · and material science.
