摘要：

A conductometric glucose sensor was fabricated by coating a twin-microband electrode with a bilayer of a membrane composed of polyaniline and glucose oxidase/gluconolactonase films. The enzyme-catalyzed hydrolysis of glucose induces a change in the conductivity of the pH-sensitive polyaniline film. The conductivity change was detected by the current flowing between the two-band electrode. The sensor demonstrates clear responses to glucose up to 1 mM.
