Abstract : A fluorescence probe with mitochondrial targeting and two-photon property, its preparation method and application in detecting and tracking endogenous H2S in samples or living cells. The fluorescent probe is prepared by a four-step preparation method and demonstrates a UV-vis absorption increment λab=395 nm and ˜43 fold higher fluorescence intensity in the presence of H2S. The probe further demonstrates stability, selectivity for H2S over competing agents and sensitivity as low as 20 nm. A method of detecting endogenous H2S rapidly in the absence of any external stimulators is provided. Samples are contacted with the probe and the changes in fluorescence are monitored to detect H2S levels. The disclosed probe is non-toxic and suitable as a biomarker and therapeutic molecule in cancer and other diseases.
