对多壁碳纳米管半乳糖传感器的检测条件进行了优化。确认其对半乳糖具有灵敏的生物响应性

表现出良好的线性和分辨力。此传感器对半乳糖摩尔浓度0.5×10-4

.5×10-2mol/L呈线性响应

检出限为1.0×10-4mol/L

响应时间为10 s

30 d后

响应电流依然保持80%。

Abstract

An amperometric galactose biosensor is formed based on the enzyme electrode with multi-walled carbon nanotubes（MWNTs） modified on Prussian blue（PB）modified glassy carbon electrode.The bioelectrochemical characterization of galactose oxidase of the galactose biosensor is studied.The experimental conditions related to the characterization of sensor have been studied in detail.It is confirmed that the electrode has sensitive biological response performance

which led to better linearity and resolution.The sensor offeres a linear range of 0.5×10-4

.5×10-2mol/L and a detection limit of 1.0×10-4mol/L.Response time is 10 s

response time remains 80 % after 30 d.
