In this study, we report on needle-like hydroxyapatite grown on the surface of calcium phosphate/blood plasma proteins biocement in simulated body fluid (SBF). Scanning electron microscope revealed the formation of nano-sized needle-like hydroxyapatite crystals on the surface of the biocement after 7 days immersion in the simulated body fluid. X-ray diffraction analysis of the biocement structures indicated that the nanoneedle crystals were hydroxyapatite. Finally Fourier transform infra-red investigations were employed to detect the functional groups of the biocement which this technique demonstrated to be hydroxyapatite.
