A water-soluble near-infrared probe for colorimetric and ratiometric sensing of SO2 derivatives in living cells.
A coumarin TCF-based water-soluble near-infrared fluorescent probe was presented, which could be used for the rapid, colorimetric and ratiometric detection of SO2 derivatives with a detection limit of 0.27 nM. Moreover, this probe could successfully image the analyte in living cells.
