摘要：
A novel biosensor, comprised of electrode of gold/multi-walled carbon nanotubes-glucose oxidase (Au/MWNTs-GOD), has been developed. The MWNTs were produced by microwave plasma enhanced chemical vapor deposition. The enzyme of GOD was immobilized using MWNTs. Performance and characteristics of the fabricated glucose biosensor were assessed with respect to response time, detection limit, pH value and storage stability. The results show that the fabricated biosensor is sensitive and stable in detecting glucose, indicating that MWNTs are a good candidate material for the immobilization of enzyme in glucose biosensor construction.
