Resumen:
Titanium is a corrosion-resistant and biocompatible material widely used in medical and dentalimplants. Titanium surfaces, however, are prone to bacterial colonization that could lead toinfection, inflammation, and finally to implant failure. Silver nanoparticles (AgNPs) havedemonstrated an excellent performance as biocides, and thus their integration to titaniumsurfaces is an attractive strategy to decrease the risk of implant failure. In this work a simple andefficient method is described to modify Ti/TiO2 surfaces with citrate-capped AgNPs. Thesenanoparticles spontaneously adsorb on Ti/TiO2, forming nanometer-sized aggregates consistingof individual AgNPs that homogeneously cover the surface. The modified AgNP- Ti/TiO2surface exhibits a good resistance to colonization by Pseudomonas aeruginosa, a model systemfor biofilm formation.
