Antibacterial Zinc Oxide Nanoparticles in Polymer Biomaterial Composites

摘要

In this study, ZnO nanoparticles reduced the activity of Staph. aureus when added to PVC/ZnO composites. Results indicated that all weight percentages of ZnO nanoparticles in PVC significantly reduced bacteria activity compared to pure polymer. This suggests that polymer and nanoparticle composites could be used for biomaterial applications prone to excessive bacterial growth, such as orthopedic implants and endotracheal tubes, due to their ability to reduce biofilm formation.
