摘要：

The performance of a bienzyme amperometric composite biosensor for the determination of short-chain alcohols is reported. Alcohol oxidase and horseradish peroxidase together with the mediator ferrocene were incorporated into reticulated vitreous carbon (RVC)-epoxy resin electrode matrices. Under the optimized experimental conditions, the composite bienzyme electrode exhibited rapid amperometric responses at 0.00V to the changes in the substrate concentration. The lifetime of each single biosensor was estimated to be ca. 20 days, and reproducible responses were obtained with different electrodes constructed in the same manner.
