Abstract

Cerium accumulation in the environment increases the health risk of humans due to the unavoidable usage of cerium in our day-to-day life. Therefore, developing a chemosensory scaffold for the rapid detection of cerium is necessary. With the objective of assessing and understanding the various factors involved in the sensing of Ce⁴⁺, this review consolidates all the 34 chemosensory molecules, mechanisms, techniques, matrices and discusses all the relevant parameters comprehensively. 23 out of 34 probes are directly utilizing the oxidative capability of Ce⁴⁺ for the detection and undergo color changes. Probes that are demonstrated with metal enhanced fluorescence exhibit lower detection limits. Based on the survey, we suggest that the investigation of the rigidity of “probe- Ce⁴⁺” and its impact on the emission/quenching should be considered for designing an efficient Ce⁴⁺ sensor. This is the first review report on the Ce⁴⁺ sensors and it could serve as a one-point reference source.

摘要

由于我们日常生活中不可避免地使用铈，环境中的铈积累会增加人类的健康风险。因此，有必要开发一种用于快速检测铈的化学感应支架。^{为了评估和理解Ce 4+}传感中涉及的各种因素，本综述整合了所有34种化学感应分子、机制、技术、基质，并全面讨论了所有相关参数。34个探针中有23个直接利用Ce ⁴⁺的氧化能力进行检测并发生颜色变化。用金属增强荧光显示的探针表现出较低的检测限。基于调查，我们建议在设计高效的Ce ⁴⁺传感器时，应考虑对“探针-Ce ⁴⁺ ”的刚度及其对发射/猝灭的影响进行调查。^{这是Ce 4+}传感器的第一份评论报告，可以作为单点参考来源。
