Abstract

Chiral carbon quantum dots (L-carbon quantum dots, L-CQDs; and D-carbon quantum dots, D-CQDs) were synthesized through the facile hydrothermal treatment of carbonated citric acid and L-cysteine (or D-cysteine). The chirality in L-CQDs and D-CQDs was demonstrated by circular dichroism. Both L-carbon quantum dots and D-carbon quantum dots could exhibit good enantioselective recognition ability.
