Insights into the Antimicrobial Mechanism of Piezoelectric Materials.

ABSTRACT: Physical disruption of bacterial integrity with piezoelectric materials offers a promising alternative to conventional bactericidal chemical treatments. In this study, we investigated the mechanisms of the antibacterial effect of mechanically stimulated poly-(vinylidene fluoride-co-trifluoroethylene) (P-(VDF-TrFE)) piezoelectric material on Escherichia coli cells with modified cell wall layers. Cells with modified peptidoglycan layer, outer membrane, or extracellular polymer matrix were tested for piezoelectric susceptibility either in direct contact with the piezoelectric material or in suspension after mechanical stimulation of the piezoelectric material, during the exponential and stationary growth phase. The results show that the P-(VDF-TrFE) material can electrostaticall
