Functional carbon nanotube material-based enzyme biosensors for glucose sensing

Carbon nanotubes exhibit excellent properties which make them a good candidate as the electrode material for bioapplications. In this paper, various carbon nanotube based electrodes were prepared by thick film technique. After enzyme immobilization, they can be used as biosensors for glucose detection. We present our fabrication steps, electrochemical measurement of functional nanotube based biosensors. Also, influences of Ph value and interferences were tested. Preliminary results show purified carbon nanotubes electrodes exhibit better electrochemical performance for glucose detection, compared with other nanotube based electrodes.
