Hydroxyapatite Nano-Particles Extracted from Miscellaneous Bestial Resources: Study of Crystal Structure and Microstructure

In this work, hydroxyapatite nano-particles were successfully synthesized via the usage of available fish, hen and bovine bones in waste foods. The crystal structure, microstructure, and functional groups of the synthesized nanostructured bioceramics were studied using X-ray diffraction (XRD), field emission scanning electron microscopy (FESEM), and fourier transform infrared spectroscopy (FTIR). It was shown that all the used natural resources provide well crystallized crystal structures of hydroxyapatite with a narrow distribution microstructure in the range of 24.4-93.4 nm. As well, it was found that the hydroxyapatite extracted from the fish bone has smaller particle size than those of the hen and bovine. Additionally, all the synthesized productions possess the same functional groups, they can be employed as promising candidates for the bone filler materials in biomedical engineering.
