以萘酚绿B为电子媒介体的葡萄糖生物传感器的研究(英文)

Study on Glucose Biosensor with Naphthol Green B as a New Mediator

首次采用了染料萘酚绿B作为葡萄糖氧化酶电极的电子媒介体制备电流型葡萄糖生物传感器.该传感器具有检测电位低,抗干扰能力强,灵敏度高等特点,其对葡萄糖的线性响应范围为1 5～18μmol/L,检测下限为0 5μmol/L及响应时间小于30s.

Naphthol green B was used, for the first time, as a new mediator in an amperometric glucose biosensor. It has been shown to be a good mediator, promoting electron transfer from glucose oxidase to graphite electrode. The biosensor shows high sensitivity to glucose at low potential with a response time of 30 s. The linear range is from 1.5 to 18 μmol/L glucose with detection limit of 0.5 μmol/L glucose.
