A ratiometric water-soluble fluorescent probe for the detection of sulfur dioxide derivative in sinusitis mice model.

Sulfur dioxide (SO) plays an extremely important role in the basic processes of physiology and pathology. As an antioxidant, SO can maintain the redox homeostasis in the cell. Excessive inhalation of SO would lead to irreparable respiratory damage, resulting in respiratory diseases, neurological disorders, and even cardiovascular disease.
