Review of diamond-like carbon films in medical applications

A review on the diamond like carbon (DLC) film as coating material for biomedical application, nowadays DLC as coating material is coming larger in biomedical application with variation of time because of its properties and biocompatibility, when we go back in history we noticed that the first report on the hard carbon films were published in the 1950s and nearly 20 years later then began worldwide doing a lot of researches activity on diamond like carbon and nowadays it is more and more for the therapeutic and diagnostic application in biomedical field. DLC films has a lot of strengths which is hemocompatibility, low friction, and low roughness, good adhesion, stability, corrosion resistance and more. When we talk about production of DLC, there are two major methods to produce the DLC which is Physical vapor deposition (PVD method) and the other method is Chemical vapor deposition (CVD method) which is the common method (widely used) to produce the diamond like carbon and its depends on using of hydrocarbon gas, and it is simple in structure compare by other procedure, it has advantages among other procedure which is low cost and low roughness and low friction. Nowadays according to Increase the world's population and the increase in the average of weights of people that caused in increasing a number of load-bearing joints that need to be replaced by artificial implants such as hip joints implant , knee joints implant all of them is coated by DLC to provide high adhesion and more, also for the DLC-coated stent it is widely used in this time, and for advanced biomedical applications (new trends) of the DLC Coatings we can use it as Nanotechnology such as biomolecular monitoring , cancer therapy and neural cell.
