In the present work, a conducting polymer, doped polypyrrole, was used to develop a gas sensor by dip-pen nanolithography (DPN). The response time of the sensor to 18 ppm CO2was 9 s. The sensor response increased linearly as the CO2concentration increased. A possible mechanism for the CO2sensing was discussed.
