Resumen:
Titanium is a corrosion-resistant and biocompatible material widely used
in medical and dental implants. Titanium surfaces, however, are prone
to bacterial colonization that could lead to infection, inflammation,
and finally to implant failure. Silver nanoparticles (AgNPs) have
demonstrated an excellent performance as biocides, and thus their
integration to titanium surfaces is an attractive strategy to decrease
the risk of implant failure. In this work a simple and efficient method
is described to modify Ti/TiO2 surfaces with citrate-capped AgNPs. These nanoparticles spontaneously adsorb on Ti/TiO2,
forming nanometer-sized aggregates consisting of individual AgNPs that
homogeneously cover the surface. The modified AgNPTi/TiO2 surface exhibits a good resistance to colonization by Pseudomonas aeruginosa, a model system for biofilm formation.
