Development of an activatable hydrogen sulfide-specific two-photon fluorescent probe for bioimaging in an air pouch inflammation model

(1) An activatable two-photon H 2 S fluorescent probe. (2) The first fluorescent probe to monitor H 2 S levels in air pouch inflammation. (3) Penetration depths up to 126 μm. (4) The fluorescence imaging of H 2 S in cells, tissue and in mice.
