Summary: The success of titanium implantation may be compromised by Staphylococcus aureus colonization and infection. To address this issue, different strategies have been explored to enhance the antibacterial properties of titanium. In this study, silver nanoparticles and a multifunctional antimicrobial peptide were used to coat titanium surfaces. The density of nanoparticles on titanium was optimized and a two-step functionalization method was used to sequentially coat the surfaces with both agents. The antibacterial effectiveness of the coatings, individually and in combination, was evaluated, and all the tested coatings showed reduced bacteria after 4 hours of incubation. However, after 24 hours of incubation, the individual antimicrobial peptide coating demonstrated greater efficacy against Staphylococcus aureus compared to the silver nanoparticles or their combination. The tested coatings were also found to be non-toxic to eukaryotic cells.
