Abstract
After plasmochemical activation, chitosan-based coatings (containing silver or gold nanoparticles) were applied on nitinol (NiTi) alloy surface to study the effect of this functionalization on i) wettability, ii) corrosion resistance, iii) release of metal ions, and iv) cytotoxicity. Surface modification of nitinol based on (1) Ar/O2/NH3 plasma treatment and deposition of chitosan/AgNPs/vit.C coating (CS/AgNPs) or (2) Ar/O2/NH3 plasma treatment and deposition of chitosan/AuNPs coating (CS/AuNPs) resulted in decrease in water contact angle (enhanced hydrophilicity), increase in surface roughness parameters, improvement of corrosion resistance, and good biocompatibility (proved on human osteoblast-like cells in vitro), when compared to both unmodified NiTi and the chitosan layer itself. The proposed surface functionalization can potentially be a powerful and promising strategy for reducing pathogenic microorganism-associated infections without harmful effects towards mammalian cells, thus facilitating proper osseointegration.
