Inside Cover: Fluorescent Probes for Hydrogen Sulfide Detection (Asian J. Org. Chem. 9/2014)

Fluorescent Probes Hydrogen sulfide (H 2 S) has an odor threshold of a mere 0.47 ppb. With a nose for a detector on every one of us it seemed, until recently, that we had surely sniffed out all sources of this toxic and foul smelling gas. H 2 S has been within us all along, and as a growing body of research shows, our understanding of its physiological effects are just beginning. In their Focus Review on page 914 ff., Ming Xian and co‐workers examine fluorescent probes for H 2 S. These compounds are the first generation of a powerful and desperately needed detection method that will sniff out, through illumination, the role that H 2 S plays in all of us.
