Abstract

A pre-oxidative amperometric glucose biosensor incorporated with carbon nanotube,ferrocenemonocarboxylic acid and PbO₂ was designed.The interferences coming from reduced substances,such as ascoribic acid and urine acid were eliminated by PbO₂.The oxidative current is linear at the potential of +0.40 V(vs.SCE) to the concentration of glucose in the range from 0.50 to 20 mmol·L^-1,and the detection limit of glucose is 0.1 mol L^-1.The relative standard deviation is 3.3% for seven successive assays at 5.0 mmol·L^-1glucose.This biosensors have been applied to determination of the glucose in serum with satisfying results.
