“…Such NIL process used a nano-template to create pattern, rather than by using a stylus, brought about relatively higher throughput. NIL has been used to create nano-patterns on various substrates for biomedical applications [ 162–164 ], or fabricate polymers [ 165 , 166 ], proteins [ 167–169 ] and DNA [ 170 ] patterns on the substrates.…”

At the time of implanting bone-related implants into human body, a variety of biological responses to the material surface occur with respect to surface chemistry and physical state. The commonly used biomaterials (e.g. titanium and its alloy, Co–Cr alloy, stainless steel, polyetheretherketone, ultra-high molecular weight polyethylene and various calcium phosphates) have many drawbacks such as lack of biocompatibility and improper mechanical properties. As surface modification is very promising technology to overcome such problems, a variety of surface modification techniques have been being investigated. This review paper covers recent advances in surface modification techniques of bone-related materials including physicochemical coating, radiation grafting, plasma surface engineering, ion beam processing and surface patterning techniques. The contents are organized with different types of techniques to applicable materials, and typical examples are also described.
