Due to the excellent mechanical properties combined with good biocompatibility thin diamond layers are considered as a promising material for biomedical applications like implant coatings. We performed tribological measurements of ultrananocrystalline diamond (UNCD) coated titanium samples against steel and diamond counterparts to investigate their friction behavior. The key property of an implant coating is the interaction with the surrounding tissue to prevent inflammatory responses but on the other hand to promote the integration of the implant into the tissue. We prepared UNCD samples with and without plasma modification of the surface and used three different cell lines related to the generation of new blood vessels and bone matter to study the effects of the different surfaces on the cell adhesion by immunostaining studies and the protein content of the cells by bioinformatic analysis of the proteome. Additionally, we aim to provide the coating with antimicrobial ability by embedding silver nanoparticles into the coating that release silver ions which are known as effective antibacterial agents.
