  Abstract:   A complex nano-hydroxyapatite (HAP) with.0.6 wt% Mg, 0.2 wt% Zn and 0.2 wt% Si was synthesized by the precipitation method. Composites of HAP with collagen (HAP-COL), HAP with chitosan (HAP-CHI) and HAP-COL-CHI were also prepared. The obtained biomaterials were characterized by X-ray diffraction (XRD), FTIR and FT-Raman spectroscopy, and by transmission electron microscopy (TEM) imaging. These biocomposites are potentially useful for hard tissue repairs and orthopedic applications.

Keywords: nano-hydroxypatite, collagen, chitosan, composites.
