This chapter reviews studies which were made together with the former BAM working group “Biomaterials and Implants” headed by Dr. Georg Berger and his co-workers Renate Gildenhaar and Erhard Lehmann. We thank Andreas Hackbarth (BAM 9.1 “Service Loading Fatigue and Structural Integrity”) for performing the mechanical stability tests. We are thankful to Birgid Strauß and Sigrid Benemann (BAM 6.8 “Surface Analysis and Interfacial Chemistry”) for the work with the SEM/EDX. Robert Koter (BAM 6.4 “Nanomaterial Technologies”) kept the complex femtosecond laser system alive.
