Original Abstract

Enhanced antibacterial properties of nanomaterials such as TiO2 nanotubes (TNTs) and silver nanoparticles (AgNPs) have attracted much attention in biomedicine and industry. The antibacterial properties of nanoparticles depend, among others, on the functionalization layer of nanoparticles. However, the more complex information about the influence of different functionalization layers on antibacterial properties of nanoparticle decorated surfaces is still missing. Here we show the array of ~50 nm diameter TNTs decorated with ~50 nm AgNPs having different functionalization layers such as polyvinylpyrrolidone, branched polyethyleneimine, citrate, lipoic acid, and polyethylene glycol. To assess the antibacterial properties, the viability of gram-positive (Staphylococcus aureus) and gram-negative bacteria (Escherichia coli and Pseudomonas aeruginosa) has been performed. Our results showed that the functional layer of nanoparticles play important role in antibacterial properties and the synergistic effect such nanoparticles and TiO2 nanotubes have had different effect on adhesion and viability of G- and G+ bacteria. These findings could help researches to optimally design any surfaces to be used as an antibacterial included the implantable titanium biomaterials.
