A Fluorescent Probe for the Fast Detection of Hypochlorite and its Applications in Water, Test Strip and Living Cells.

Hypochlorite (ClO-) mediated by oxidative stress play an important role in the body's defense system due to their physiological and pathological significance. In this work, a new and simple probe was designed and synthesized to detect hypochlorite. This probe could rapidly respond to hypochlorite in a short time (20 s) in aqueous media, and showed excellent selectivity and sensitivity, and a wide pH range of 3 ̶ 12, as well as the low detection limit of 1.44 nM. In addition, it was successfully applied to the detection of ClO- in water sample, test paper experiment, and cell imaging.
