RESUMO
In our study, various bacteria, including Gram-negative (Pseudomonas aeruginosa, Escherichia coli, Acinetobacter calcoaceticus, Serratia marcescens, Shewanella oneidensis) and Gram-positive (Bacillus subtilis) bacteria, were straightforwardly immobilized into the conducting polymers (CPs) by electrochemical deposition. The doping state of bacteria in the polymer films (polypyrrole and poly(3,4-ethylenedioxythiophene)) varied according to the polymerization conditions. The viability of bacteria in the polymers and of those adsorbed on various substrates was evaluated. The activity of bacteria doped on the polymer film was evaluated by cyclic voltammetry in a thin-layer cell.

We demonstrate a simple manipulation of gold nanoparticles that creates a structure-dependent nanometer-scale antenna on the surface of bacteria. Our studies illuminate the concept of the "effective use of light" based on the absorption and emission of light by antennas formed on bacteria.
