Fluorometric detection of tyrosine and cysteine using graphene quantum dots

Herein, a facile fluorescence method has been developed for the detection of tyrosine (Tyr) and cysteine (Cys) based on graphene quantum dots (GQDs) as a sensitive probe. Tyr could be oxidized to dopaquinone by tyrosinase catalyzation, which could efficiently quench the fluorescence of GQDs through...
