A near-infrared fluorescence off–on probe for sensitive imaging of hydrogen polysulfides in living cells and mice in vivo†
Abstract
A new hemicyanine-based near-infrared fluorescence off–on probe with phenyl 2-(benzoylthio)benzoate as the recognition moiety to trap hydrogen polysulfides (H2Sn, n > 1) is developed, and is used for the sensitive imaging of H2Sn in cells and mice in vivo.
