Reaction-based fluorescent probes for sulfane sulfur and the application in bioimaging

摘要

Reaction-based fluorescent probes are provided which detect, for example, biologically important sulfane sulfur species (persulfide, polysulfide, and elemental sulfur) in, for example, complex and living systems. The probes are high in selectivity and sensitivity to sulfane sulfurs. Moreover, probes are suitable for bioimaging sulfane sulfurs in living cells.
