DLC (Diamond-Like Carbon) thin films which are synthesized by RF-PECVD on medical grade steel substrates will be evaluated in terms of its antibacterial properties against to Mycobacterium chimaera. In the world of health, cardiac surgery infection caused by the Mycobacterium chimaera is becoming an increasingly important emerging problem. Heater Cooler Units (HCU’s) which is an essential tool used for cardiac surgeries and also other issued equipment are contaminated by Mycobacterium chimaera. This is one of the critical problems that should be solved with appropriate technics/methods. Diamond Like Carbon (DLC) nano films are good candidates as an antibacterial coating on the critical surfaces. Due to its unique tribological, physical and mechanical surface properties, DLC films can combine three important antibacterial leading characteristics in its body; these are namely anti-adhesive, contact active and biocide release characteristics. One of the aims of this study is to search, characterize and enhance the antibacterial properties of DLC on medical tools and together with optimum surface properties.
