As a reducing biothiol, cysteine participates in the redox process in cells and plays an important role in maintaining cellular homeostasis and organismal health. Previous studies showed that the occurrence of many diseases was often accompanied by changes in the level of cysteine in the body. Therefore, real-time monitoring of changes in cysteine content in the body is of great significance for the prevention and treatment of diseases. Traditional methods for the detection of cysteine in biological samples have strict test conditions and poor biocompatibility. The fluorescent probe developed based on fluorescence imaging technology possesses the advantages of high specificity, strong tissue penetration and non-invasiveness, and can recognize real-time quantitative monitoring of cysteine in organisms. In this review, the construction strategies, recognition mechanisms and applications of cysteine fluorescent probes in the field of medical testing are summarized, specifically involving Parkinson’s disease, Alzheimer’s disease, liver injury, arthritis, depression and diabetes, and the signal response and biological applications of fluorescent probes in the development of these diseases are analyzed. It will provide more accurate measurement methods and diagnostic methods for human health and disease research, and also provide new ideas and methods for the development of fluorescent probes.
