The antibiotic resistance of bacteria is raising major concerns in medicine resulting, e.g., in serious medical complications during the bone replacement. Thus, it is important to design and tailor new biomaterials which on the one hand prevent bacterial adhesion and on the other hand promote osteoblast growth. Titanium is the typically used bone implant material. However, further improvements of titanium-based implants are needed to enhance their antimicrobial resistance. In this work, we focus on the functionalization of titanium surfaces with graphene-based materials which exhibit antimicrobial activity and biocompatibility.
