Biomaterials exhibit various degrees of compatibility with the harsh environment within a living organism. They need to be nonreactive chemically and physically with the body, as well as integrate when deposited into tissue.<ref>Saberi, A.; Bakhsheshi-Rad, H.R.; Abazari, S.; Ismail, A.F.; Sharif, S.; Ramakrishna, S.; Daroonparvar, M.; Berto, F.

Often modifications to the surface of a biomaterial system are required to maximize performance. The surface can be modified in many ways, including plasma modification and applying coatings to the substrate. Surface modifications can be used to affect [[surface energy]], [[adhesion]], [[biocompatibility]], chemical inertness, lubricity, [[Sterilization (microbiology)|sterility]], [[asepsis]], [[Thrombosis|thrombogenicity]], susceptibility to [[corrosion]], degradation, and [[hydrophile|hydrophilicity]].
