Surface Modification Techniques for Bio-Materials

Abstract

The increasing population demands materials with higher expectations associated to quality of life cropping up from an aging population. Recently there has been an ever-increasing search for novel biomaterials as the material needs for complex biomedical devices shoots up with time. This chapter discusses the different technology used for surface modification of material for biomedical applications. The surface modification process is generally used to obtain the antibacterial properties, antifouling, enhanced mechanical properties, reduced cytotoxicity, anti-inflammatory potential, improved hemocompatibility, and osseointegration capabilities. Various metallic materials are considered as biocompatible materials such as titanium alloys, stainless steel alloys, and magnesium alloys. Moreover, surface modification of dental implants and polymers were reviewed, and recent progress and challenges in application of biomaterials are reported related to the surface modification process.
