We report the application of a chemodosimeter {'}turn on{'} fluorescent probe for detecting endogenous H2S formation in cancer cells. Mito-HS showed a bathochromic shift in the UV-vis-absorption spectrum from 355 nm to 395 nm in the presence of H2S. Furthermore{,} it showed an [similar]43-fold fluorescence enhancement at [small lambda]em = 450 nm in the presence of H2S (200 [small mu ]M). The cancer cell-specific fluorescence imaging reveals that Mito-HS has the ability to distinguish cancer cells from normal cells based on the level of endogenous H2S formation. In due course{,} Mito-HS would be a powerful cancer biomarker based on its ability to estimate endogenous H2S formation in living cells.
