摘要
A glucose biosensor was constructed by electrochemical adsorption of glucose oxidase (GOD) in microporous polyacrylonitrile (PAN), which was synthesized by single rare-earth catalyst-Y(OAr)(3). The biosensor shows a fast response, good operational stability and reproducibility. The influences of molecular weight of polymer, pH, operating potential and temperature on the biosensor response were explored by amperometric method. The apparent activation energy and optimum pH of enzyme-catalyzed reaction are 35.9 kJ mol(-1) and 6.2, respectively. (C) 2002 Elsevier Science BY. All rights reserved.
