Hydrogen sulfide (H2S) is an important signaling molecule with potent cytoprotective
actions. Current results strongly suggest that modulation of H2S levels could have potential
therapeutic values for a number of disease states, but its exact mechanisms of action are still
unclear. A number of fundamental issues must be addressed to advance our understanding
of the biology and clinical potential of H2S in the future. It is important, therefore, to
understand the chemistry and properties of H2S and to appreciate the limitation and errors …

In comparison with other biological detection technologies, fluorescence bioimaging
technology has become a powerful supporting tool for intracellular detection, and can
provide attractive facilities for investigating physiological and pathological processes of
interest with high spatial and temporal resolution, less invasiveness, and a rapid response.
Due to the versatile roles of hydrogen sulfide (H2S) in cellular signal transduction and
intracellular redox status regulation, fluorescent probes for the detection of this third …
