A Forster Resonance Energy Transfer Switchable Fluorescent Probe With H2S-Activated Second Near-Infrared Emission for Bioimaging.

ABSTRACT: Real-time and accurate detection of endogenous hydrogen sulfide is of great biomedical significance. Here, a FRET-based fluorescent probe for ratiometric detection of H2S was designed to comprise an AIE luminophore TPE as an energy donor and a monochlorinated BODIPY dye as an energy acceptor and H2S-responsive site. Such a designed probe showed H2S-dependent ratiometric and light-up NIR-II emission, enabling accurate imaging of H2S-rich cancer cells and identification of H2S-rich tumors with high resolution.
