Abstract

Carbon quantum dots (CQDs) obtained from polyethylene glycol were demonstrated to be easy-to-use photoluminescence probes for the detection of glucose. Here, the photoluminescence of CQDs was significantly enhanced by H2O2 produced from glucose oxidase-catalyzed oxidation of glucose. Moreover, CQDs showed an ultrasensitive detection of glucose, with a detection limit of up to 1 nM.
