ABSTRACT

Si quantum dots have been demonstrated to be environmentally friendly photoluminescence probes and their fluorescence was quenched by H(2)O(2) that was produced from the glucose oxidase-catalyzed oxidation of glucose. This strategy could be used to detect glucose with high sensitivity and selectivity.
