Description
Summary:Since Hydrogen Sulfide (H<sub>2</sub>S) was recognized as a gas transmitter, its detection and quantification have become a hot research topic among chemists and biologists. In this area, fluorescent probes have shown great advantages: fast and strong response, low detection limit and easy manipulation. Here we developed a new fluorescent probe that detected H<sub>2</sub>S selectively among various bioactive and inorganic salts. This probe was based on the core structure of fluorescein and reacted with H<sub>2</sub>S through azide-reduction. Great linearity was achieved correlating fluorescence intensity and H<sub>2</sub>S concentrations in solution. The detection of H<sub>2</sub>S in cancer cells was also achieved.
