Review of the detection of metal ions using fluorescent probes

Abstract

Metal ions, essential for numerous physiological functions of the human body require accurate monitoring in order to gain precise knowledge of the health status of people. As fluorescent probes advances, the level of metal ions can be measured with high selectivity and sensitivity. Allowing the homeostasis of numerous metal ions to be maintained easily. Fluorescent probes are a hot area of research, providing a prospective tool for the detection of metal ions and to provide critical statistics in maintaining the homeostasis of the human body. This article introduces several fluorescent probes on the detection of both essential and toxic metal ions. It gives a review about the recent development in the detection of metal ions using fluorescent probes. This article explains the mechanism of recognition of each fluorescent probe and summarizes the results obtained from experiments. Outlining the advantages and shortcomings of each fluorescent probe. It includes novel fluorescent probes based on uncommon mechanisms.
