Nanostructured biomaterials are promising because their similarities with nanostructured components of the extracellular matrix. Diamond-like carbon (DLC) films gather physical and chemical properties such as high hardness, chemical stability, visible transparency, low friction and high resistance to wear. The deposition of hydroxyapatite (HAp) on DLC surface has been studied in order to improve DLC bioactivity, aiming this new composite applicability in bone-regenerative medicine. The aim of this work was to study the in vitro process of HAp/DLC and HAp/TiO2-DLC composites biomineralization, to develop new designs of HAp crystals, seeking to enhance the characteristics and properties of HAp/DLC and HAp/TiO2-DLC composites.
