Abstract

We present a novel fabrication method by using dip pen nanolithography with Poly (3,4-ethylenedioxythiophene) poly(styrenesulfonate) (PEDOT:PSS) for nitric oxide (NO) gas sensor in this report. PEDOT is a kind of conducting polymer which will change its conductance upon NO adsorption. Herein, we have used PEDOT with traditional thick film and DPN nanowires across electrodes. By using traditional thick film device, the lowest detection limit for NO is 3.87 ppm. The preliminary results of DPN nanowires can have aspect ratio (L/W) for up to 220 times and thus have large sensing surface area for higher sensitivity.
