On–off–on detection of Hg2+ and GSH using green-synthesized CQDs from T. indica leaves for the first time.
Herein, we employ pH-dependent solubility equilibrium to develop the one-pot aqueous synthesis of dual-color emission fluorescent carbon nanosphere (DFCSs) with novel physicochemical properties.
Fluorescent carbon dots derived from peanut shells were prepared via a pyrolysis approach and used for living cell imaging.
