Precisely Defined Heterogeneous Conducting Polymer Nanowire Arrays - Fabrication and Chemical Sensing Applications

Heterogeneous conducting polymer nanostructures are fabricated using a newly developed method. Completely isolated nanowires of several conducting polymer materials can be fabricated side-by-side with perfect registry to each other on a rigid or flexible substrate. Results of a chemical sensing study using PPY and PEDOT nanowires are presented (see figure).
