Abstract: Metal ions are widely distributed in nature and they have key roles in the environment,bioscience and medical science. Some metal ions,such as Hg²⁺,Fe³⁺,Cu²⁺,Zn²⁺ and Al³⁺,play important roles in the physiology and pathology of organisms. An excess or deficiency of these metal ions would lead to physiological dysfunction and cause a variety of diseases. Recently,reaction-based fluorescence probes have attracted considerable attention due to their high sensitivity and good selectivity. This review mainly focuses on reaction-based fluorescence probes for the detection of metal ions in the past five years. The design and synthesis of probes,their sensing mechanisms and their applications were summarized. Currently,the reaction-based fluorescence probes are still in their initial stages and hence many problems need to be solved. With the resolution of these problems,reaction-based fluorescence probes would show higher sensitivities with less reaction-time and possess wider applications. In the future,reaction-based fluorescence probes should show efficient development in biological detection and expand practical applications.
