Biomedical Applications of Nanostructured Carbon-Based Coatings

The repair and replacement of diseased tissues and injured organs of humans is increasing day by day. Long lifetime and high biocompatibility are two main factors in the process of designing and manufacturing components used in medicine (such as biological implants). Wear is one of the biggest problems with the parts used in medicine. The protective coatings can be used to improve the wear resistance. On the other hand, most of the biodegradable parts are metallic, and there is a possibility that dangerous metal ions will be released from their surface and enter the body. Protective coatings can be used as a barrier against the release and penetration of ions affect the body's tissues. Numerous studies have shown that nanostructured diamond-like carbon coatings (DLC) have the ability to create these properties on the surface of biological components. These coatings are produced with several methods, such as the physical vapor barrier layer (PVD) and the chemical vapor barrier chemical layer (CVD), and by doping elements of nitrogen, copper and silver, unique properties can be created on their surface. The present paper includes studies in the field of using diamond carbon nanostructured coatings such as (DLC) in medical applications such as orthopedics, cardiovascular system, ophthalmology and dentistry.
