摘要	In this paper, utilizing dual-emission carbon nanodots (DECNDs), both single signal and ratiometric detection could be developed for glucose and glucose oxidase (GOx) with high sensitivity and selectivity. Glucose could be efficiently catalyzed by GOx to generate gluconic acid and hydrogen peroxide (H2O2); in the presence of Fe2+, based on Fenton reaction (Fe2+ and H2O2), hydroxyl radicals ((OH)-O-center dot) could be easily achieved and caused the fluorescence quenching of DECNDs. Under optimum conditions, this fluorescent nanosensor showed excellent sensitivity with the limit of detection (LOD) of glucose 0.03 mu M and LOD of GOx 1.5 10(-5) U/mL. The proposed method was successfully applied to the determination of glucose in real samples with satisfactory recoveries. (C) 2016 Elsevier B.V. All rights reserved.
