A rapid turn-on fluorescent probe is proposed for the sensitive and specific determination of ascorbic acid based on carbon dots–MnO2 nanocomposites.
Herein, a ratiometric fluorescence strategy based on the MnO2 nanosheets and nitrogen, chlorine co-doped carbon dots (N, Cl-CDs) was constructed for selective determination glutathione (GSH) and the absolute fluorescence quantum...
