Herein, our group developed a fast response fluorescent probe (Flu-N3) for H2S on the basis of the 7-amino-4-methylcoumarin and fluorescein FRET system with high sensitivity and selectivity and a low detection limit of 0.031 μM. Moreover, the probe was successfully applied to image exogenous and endogenous H2S in living cells and nude mice.
