“Turn-on” fluorescent probe for detection of H2S and its applications in bioimaging

Based on the coordination reaction between probe and H2S under mild conditions, we herein report a turn-on fluorescent probe which achieves real-time detection of H2S (within 10 min), a good linearity range and a low detection limit (0.052 μM). The application of this fluorescent probe was demonstrated by fluorescent imaging in A549 cells.63
