In recent years, label-free detections of biomolecules have attracted great attention in many fields of life science such as genomics, clinical diagnosis, and practical pharmacy. In this article, we review electrochemical amperometric biosensors based on carbon nanotube (CNT) electrodes. In electrochemical detections, CNT electrodes promote electron transfer reactions on CNT surfaces. Since CNTs have a large specific surface area, the direct synthesization of CNTs on electrodes in amperometric biosensors is expected to significantly enhance electroactive surface area. In this review, we discuss the technology and performance of the electrochemical biosensors based on CNT electrodes and describe microfludic chips with multibiosensors based on CNT electrodes for commercialization.
