Surface modification using plasma and ion beam processing can significantly change the chemical and physical characteristics of biomaterial surfaces, such as their structure, composition, surface wettability, electrical properties, mechanical properties, electrochemical properties, etc. This kind of surface processing, sometimes in combination with other techniques such as chemical or biochemical methods, can be used to form novel biomaterial surfaces that are anticoagulant, antibacterial, bioactive, biomimetic, wear resistant, and more. In this paper we describe the application of plasma and ion beam processing to the field of biomedical materials.
