ONOO−, produced by the diffusion-controlled reaction of nitric oxide and superoxide radicals, is a strong oxidizing and nitrating agent that causes damage to DNA, proteins, and other biomolecules in cells. Since ONOO− is characterized by its short lifetime, high reactivity, and low concentration under physiological conditions, and the pathophysiological roles it plays in biological systems are not yet fully understood, it is of great significance to develop highly sensitive and selective detection technologies to achieve real-time dynamic monitoring of ONOO−. In this paper, we review the research progress of ONOO− fluorescent probes in disease-related processes in the recent 5 years, revealing the potential role of ONOO− in various diseases, such as inflammation, tumors, liver injury, and brain diseases. Finally, the bottlenecks in the development of ONOO− probes and future trends are discussed, which will promote the application of ONOO− probes in chemistry, biology, and pharmacology.
