The mechanism of the formation of a self-aligned hydroxyapatite (HAP) nanocrystallite structure was examined. It is found that the highly ordered HAP nanocrystallite assembly is attributed to the so-called self-(homo)epitaxial nucleation and growth. On the other hand, according to this mechanism, a high supersaturation will give rise to a random assembly of HAP crystallites. The effects of ions, biosubstrate, and supersaturation on the micro/nanostructure correlation between substrate and biominerals as well as their implications in hard tissue formation were examined. Surprisingly, some biomolecules are found to be able to suppress the supersaturation-driven interfacial structure mismatch and hence promote the well aligned HAP pattern formation.

In this research, HAp nanocrystals were synthesized using conventional wet chemical precipitation methods using various organic modifiers, including urea, palmitic acid, and naphthalene. Ethanol and isopropyl alcohol (IPA) were used as solvents in this process. Different characterization techniques, namely X-ray diffraction (XRD), scanning electron microscopy (SEM), and UV-vis absorption spectroscopy, were employed to ascertain the formation of HAp nanocrystals.

Hydroxyapatite (HAp) [Ca(PO)(OH)] is remarkably similar to the hard tissue of the human body and the uses of this material in various fields in addition to the medical sector are increasing day by day. In this research, mustered oil, soybean oil, as well as coconut oil were employed as liquid media for synthesizing nanocrystalline HAp using a wet chemical precipitation approach. The X-ray diffraction (XRD) study verified the crystalline phase of the HAp in all the indicated media and discovered similarities with the standard database.

The bones of two fish species, and , were chosen in this research for evaluating their photocatalytic efficacy under solar radiation. The fish bones were isolated and conditioned before analyzing crystallographic parameters. The samples were characterized by using different instrumental techniques such as Fourier Transform Infrared (FTIR), X-ray diffraction (XRD), Energy Dispersive X-ray (EDX), Field Emission Scanning Electronic Microscopy (FESEM), and optical bandgap.

Article Synopsis
- The mineralization of hydroxylapatite (HAp), crucial for bone formation, occurs through nontraditional routes influenced by organic compounds, particularly the small organic molecule citrate.
- Research shows that citrate stabilizes both prenucleation species and a liquid-like calcium phosphate precursor, which may enhance the mineralization process within collagen fibrils before any solid structure forms.
- The study reveals that HAp formed from amorphous calcium phosphate in the presence of citrate results in unique nanoplate structures similar to natural bone, suggesting that citrate plays a significant role in the mineralization process and challenges existing theories about HAp formation.
