By coupling the Fenton reaction with the glucose oxidase (GOD)-catalyzed reaction, we have developed a fluorometric method for the determination of glucose; the linear response range and the detection limit are 0.108 - 2.59 µg/ml and 0.0432 µg/ml, respectively. This approach is selective and has the advantages of using inexpensive reagents and avoiding interferences. Satisfactory results were obtained for the determination of glucose in human serum samples.
