Assessment of Polarized Piezoelectric SrBi4Ti4O15 Nanoparticles as an alternative antibacterial agent

Strontium bismuth titanate nanoparticles (SrBi4Ti4O15/SBT NPs,) and their polarized counterparts were prepared to assess their antibacterial efficacy on biomaterials. The structural properties of the SBT NPs were performed by X-ray diffraction and the antibacterial efficacy was evaluated against Staphyllococcus aureus (S. aureus) pathogenic bacteria. Significant antibacterial activity of polarized SBT specimen was observed against S. aureus bacteria. Results presented in this work confirmed that polarized SBT can effectively combat bacterial growth and prevent biofilm formation activity of pathogenic bacteria and hence they can be used as alternative antimicrobial agents.
