Amorphous calcium phosphate (ACP) is an essential mineral phase found in human bone which acts as a precursor for the hydroxyapatite apatite. In the present study, ACP was synthesized from eggshells, a natural resource of calcium, by rapid precipitationmethod under controlled experimental conditions. X-ray diffraction pattern confirmed the amorphous nature of the egg shell derived ACP (EACP). Infrared spectroscopy showed a single peak without splitting in the region of 600-500 cm-1 corresponding to P-O anti-symmetric bending mode which also indicates lack of crystallinity in EACP nanoparticles. EACP analysis using transmission electron microscopy indicates nanosized particles with needle shaped morphology compared to spherical shape ACP nanoparticles formed using synthetic calcium nitrate. Presence of minor amount of Mg, Sr, Si and Na ions inherited from the eggshell in EACP was also confirmed by inductively coupled plasma atomic emission spectroscopy. As these ions are also crucial for bio-mineralization of eggshell and needle morphology is similar to the morphology of apatite present in human bone, the EACP may have beneficial role in various bone tissue engineering applications. © 2017 American Scientific Publishers.
