Proliferation of Bovine Albumin Serum on Nano-Scale Titanium Nitride Coated Stainless Steel Substrates for Biomedical Applications

Biocompatible and corrosion resistant coatings are frequently used to protect and enhance the life time of bio-implants. TiN (titanium nitride) is being used as coating material on different surgical and orthopedic implants due to its excellent biocompatibility. TiN coatings are attractive because of low coefficient friction, high hardness, chemical inertness and smooth surface finish, which they will provide to biochemical devices. These coatings were prepared by PVD (physical Vapor deposition) technique on SS 304L plates to investigate the protein adhesion on coated stainless steel samples. The protein adhesion and growth of Bovine Albumin Serum (blood protein) on coated samples was checked. Surface of coated material and protein growth on coated material was investigated using AFM (atomic force microscope), SEM and FTIR.
