Bone like hydroxyapatite (nHAp) crystals was synthesized via an in situ biomimetic process in presence of wheat starch. The effect of polymer concentration alteration on the final structure of nHAp crystals was investigated. Formation of the crystalline nHAp at room temperature was confirmed by X-ray diffraction (XRD) and Fourier transform infrared spectroscopy (FT-IR). Size and morphology of the nHAp samples were characterized using scanning and transmission electron microscopy (SEM and TEM). Prepared HAp in absence of biopolymer has a different morphology from samples which are synthesized in presence of different concentration of starch. Polymer as a templating agent has influence on shape of the HAp nanocrystals precipitate in an aqueous solution of wheat starch. It leads to formation of rode like nHAp which is similar to this inorganic component in body.
