Spontaneous adsorption of silver nanoparticles on Ti/TiO₂ surfaces : Antibacterial effect on "Pseudomonas aeruginosa"

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 excel...
