We have investigated the electrical properties of a conducting polymer(ORMECON¹M L5005) for electrochemical DNA hybridization sensors. Conducting polymers are known as good candidates for chemical sensors because of their high conductivity and porosity which is beneficial to enhance the sensitivity of sensors. DNA sensors coated with the conducting polymer have been fabricated with the various sizes of gap electrodes. The gap distance in DNA biosensor electrodes is also an important element to affect the sensitivity. It was designed in the order of microns and the order of nanometers to investigate the effects of electrode gap distance.
