【 摘 要 】

A novel plasma treatment involving the deposition of ethylene glycol plasma polymer-coated titanium nanoparticles on a 316L stainless steel surface is presented. The surface properties of SS316L modified with these coated nanoparticles were compared to untreated SS316L. The deposition of ethylene glycol plasma polymer-coated nanoparticles confers properties to the surface making it more biocompatible, which is beneficial in applications of SS316L as a blood-contacting implant (e.g. vascular stents, heart valves). These properties include increased hydrophilicity and general corrosion resistance of the surface, and reduced substrate-dependent denaturation of adsorbed protein fibrinogen. (C) 2009 Elsevier B.V.
