基于电解质门控石墨烯晶体管的葡萄糖传感器

摘要

A solution-gated graphene field effect transistor is used to develop a sensitive glucose sensor. The sensor can be used for the determination of glucose with a concentration of as low as 1 × 10 -6 mol/L without any nanomate-rial modification for the Pt gate electrode. With some advantages like low-cost, easy fabrication, low working voltage, and good biocompatibility, this type of biosensor will be an excellent candidate for the applications of enzymatic sensing.%利用电解质门控石墨烯场效应晶体管制备了一种高灵敏的葡萄糖传感器.即使不采用纳米修饰的铂金栅电极，这种传感器对葡萄糖的检测极限已可达到1×10-6 mol/L.该器件具备成本低、易制备、工作电压低及生物兼容性好等优点，可广泛用于酶生物传感器的研究.
