Coumarin-coupled receptor as a membrane-permeable, Cu2+-selective fluorescent chemosensor for imaging copper(II) in HEPG-2 cell
A novel fluorescent chemosensor 1 for imaging labile Cu2+ in living biological samples was designed and synthesized; it exhibits very strong fluorescence responses to Cu2+, and its LSM images strongly support the existence of Cu2+ in HEGP-2 cell.
