Electrochemical synthesis of small-sized red fluorescent graphene quantum dots as a bioimaging platform

We report water-soluble, 3 nm uniform-sized graphene quantum dots (GQDs) with red emission prepared by electrochemical exfoliation of graphite in K2S2O8 solution. Such GQDs show a great potential as biological labels for cellular imaging.
