Conducting polymers, mainly polyaniline (PANI) and polypyrrole (PPY) with positive charges bind to the negatively charged bacterial membrane interfere activities. After this initial electrostatic adherence, conducting polymers might partially penetrate interact other intracellular biomolecules. can form polymer composites metal, metal oxides, nanoscale carbon materials as a new class of antimic...
