Carbon nanotube (CNT) is useful electrode material for electrochemical biosensors because of its wide potential window and rapid electron transfer kinetics. Excellent anti-fouling properties and high sensitivity in biomolecule detection of CNT have been reported. The signal current density, hence the sensitivity can be increased drastically by introducing redox cycle in detection process. In this work, we have fabricated interdigitated electrodes with a CNT thin film to realize high-sensitivity electrochemical biosensors based on the redox cycle.
