Detective work: Three highly sensitive and selective fluorescent probes for the detection of H2S have been developed. Two detect by reduction an azide moiety to amine group, which changes into their forms generates a signal. In third method, signal is created using as nucleophile in reaction that unmasks fluorescein.
