Abstract
According to reports, coating implants with hydroxyapatite (HAp) promotes bone repair and combines the biological effectiveness of the material with the mechanical properties of standard metallic implants. In this contribution, bioactive nanographite particles were synthesized using a novel technique to stimulate HAp deposition using a biomimetic method. The rapid breakdown ionization (RBA) technique was used to synthesize graphite nanoparticles. The electrophoretic deposition (EPD) technique was utilized to deposit the nanoparticle on titanium substrates. Scanning electron microscope (SEM) images showed the creation of nanoparticles with a size of around 65nm. An X-ray diffraction (XRD) test confirmed the polycrystalline structure of graphite with a dominant peak (002). UV-VIS absorption and FTIR spectra confirmed the production of graphite powder. To test the bioactivity of the graphite layer, it was immersed in simulated body fluid (SBF) for 30 days. The formation of a HAp layer on graphite is depicted by an XRD pattern, and SEM images illustrate nanoclusters of this layer.
