Biofunctionalization of Porous Ti Substrates Coated with Ag Nanoparticles for Potential Antibacterial Behavior

Ti prosthesis have shown better biological compatibility, mechanical performance, and resistance to corrosion in cases of bone replacements. Nevertheless, fully dense connection with bone-host tissues show stress-shielding phenomenon that, together the development frequent undesirable microbial infections, may lead implant failures. To overcome these issues, present study aimed at a novel combination chemically functionalized porous substrate potentially therapeutic AgNPs coating. Fully substrates (30 60 vol.%, 100–200 355–500 μm, as spacer particles) were studied. surface was treated acid or basic medium followed by silanization deposition “submerged” “in situ” methods. In general, for similar porosity, decreased pore size increased. Acidic reagent submerged methodology best substrates. Hence, they also employed Depending on porosity substrates, variations can be observed both degree agglomeration deposited AgNPs, entailing differences antibacterial behavior samples.
