摘要：

<正>An amperometric glucose biosensor based on a tin oxide （SnO2） electrode has been developed.The SnO2 electrode is prepared by depositing the SnO2 thin film onto a carbon electrode.To fabricate the SnO2 amperometric glucose biosensor,the glucose oxidase and electron transfer mediator （ferrocenecarboxylic acid,FcA） are coimmobilized on the SnO2 electrode using polyacrylamide.The detection range is up to glucose concentration of 520mg/dl as the applied potential is set at 300mV. Moreover,the most merit for the SnO2 electrode as the base electrode of the SnO2 amperometric glucose biosensor is that it can be operated at 150mV constant applied potential.The interference reduction,detection range,sensitivity and linearity are improved as the SnO2 thin film is deposited onto a carbon electrode.Furthermore,due to the low cost substrate and simple fabrication characteristics,a disposable amperometric glucose biosensor based on the SnO2 electrode has been realized in this study.
