Description
Summary:	[Display omitted] •Strontium bismuth titanate (SBT) nanoparticles were evaluated as antibacterial agents.•The entire bacteria were destroyed after 30 h bacteria culture on the polarized SBT.•Only 24 % of the bacteria were destroyed by the unpolarized specimens after 30 h of culture.•Polarized SBT can effectively combat bacterial growth and prevent biofilm formation of pathogenic bacteria.•It can be considered as an alternative antimicrobial agent. Nanoparticles of strontium bismuth titanate (SrBi4Ti4O15/SBT NPs), along with their polarized counterparts, were prepared and their ability to combat bacterial growth on the surface of biomaterials was assessed. The structural properties of the SBT NPs were analyzed using X-ray diffraction, and their effectiveness against Staphylococcus aureus pathogenic bacteria was evaluated. While the 30 h bacteria culture results showed that the bacteria were entirely destroyed by the polarized SBT, only 24 % of the bacteria were destroyed by the unpolarized specimens The results showed that polarized SBT was significantly effective against Staphylococcus aureus bacteria, and can effectively combat bacterial growth and prevent biofilm formation of pathogenic bacteria. Hence, it can be considered as an alternative antimicrobial agent.
