Surface modification of a commercial bone plate (Ti6Al4V) implant for improved antibacterial and cytocompatibility via thermal dewetting of a silver thin film

“…The untreated specimen shows 14.35% of elongation whereas the treated sample shows 15.26% of elongation. Therefore, the improvement in the mechanical property of annealed titanium alloy is desirable for a longer life of implant [26][27][28][29][30]. Hence, it is confirmed that the surface modification does not deteriorate the mechanical properties of implants.…”

Antibacterial Silver-Nanoparticle-Coated Stainless Steel Nails for Implant-Associated Osteomyelitis

“…To experimentally determine the optimal coating conditions, 316L stainless-steel (SS) with a diameter of 6 mm at the base and the samples were divided into two groups: one with the sputtering process variables parameterized by time (1, 2, 4 h), and the other with the sputtering process variables parametrized by a hybrid gas of hydrogen (H 2 ), methane (CH 4 ), and argon (Ar). Vacuum extraction was continued for approximately 0.5 h or until the air pressure in the chamber achieved a vacuum level of 1.33 Pa. After preliminary screening, the gas flow rate of H 2 :Ar:CH 4 was determined as 300:50:5 at a constant pressure of 400 Pa. Silver nanoparticles were deposited onto the 316L SS by Ag-aspsm technology . Samples were subjected to Ag-aspsm for 1, 2, or 4 h (designated 1h-Ag-aspsm@SS, 2h-Ag-aspsm@SS, and 4h-Ag-aspsm@SS, respectively).…”
