Abstract

We have fabricated electrochemical biological sensors based on directly synthesized carbon nanotube (CNT) electrodes. Since CNTs have a large specific surface area, the direct synthesis of CNTs on electrodes in amperometric biosensors is expected to significantly enhance electroactive surface area. Moreover, in electrochemical detections, CNT electrodes promote electron-transfer reactions on CNT surfaces. In this section, we have investigated the technology and performance of the electrochemical biosensors based on CNT electrodes and described microfluidic chips with multibiosensors based on CNT electrodes for commercialization.
