Abstract

One example for the medical application of nanodiamonds is their use in orthopedic implants. Detonation generated nanodiamonds (DND) are of great interest, because they are able to strengthen bone tissue, producing tougher and more flexible artificial bone implants. Carbon-based materials can be used to replace natural collagen in bone, in which the main inorganic ingredient is the calcium phosphate (CaP) phase, namely hydroxyapatite (HA). Collagen is the organic part of bone that is based on carbon and is of the same size as DND. In this work, we present the deposition of CaP through DND on TiCu alloys by their immersion in a mixture of simulated body fluid (SBF) and a suspension of DND. The layers were characterized by SEM, EDX, coherence probe microscopy and Raman spectroscopy. It was found that DND produced a stable aqueous suspension in SBF, and was able to stimulate the growth of CaP layers on the surfaces of TiCu substrates..
