摘要：
Carbon quantumdots (CQDs) obtained frompolyethylene 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 ultra-sensitive detection of glucose, with a detection limit of up to 1 nM.
