Outline of Final Research Achievements

In this project, we have developed conducting-polymer based electrochemical and optical sensor devices. Microbial species usually have negative charges on their surfaces, and easily doped with conducting polymers. The Polypyrrole/microbe films are expected to be electroactive and have functionality based on living microbe activity. The results outlined here are 1) preparation and evaluation of bacteria-polypyrrole films, 2) preparation and evaluation of bacteria-PEDOT films, 3) application of these films, and 4) fabrication of optical devices using gold nanoparticle-polyaniline composite materials.
