A Review on Nano Hydroxyapatite Fabrication Techniques

Bio ceramics that exhibit positive interactions with human tissues can be used in various biomedical applications. A strong bone bonding is triggered by the natural and synthetic bio ceramics when used as implants. One of the most common calcium phosphate bio ceramic used as biomaterial is hydroxyapatite. The structure and composition of hydroxyapatite analogous to the inorganic portion of bone and teeth, thus it has endless biomedical applications. As a result, demand for hydroxyapatite nanoparticles has risen over the last decade. Several synthesis methods are followed to prepare nano HAp such as dry, wet, high temperature and combination techniques. Synthesis from biogenic sources like bone waste, egg shell and exoskeleton of marine animals are also in practice. Various preparation methods results HAp nanoparticles of various morphologies, crystallite size and phases. Also the processing factors in different synthesis methodologies influence the physical, chemical, and biological properties of hydroxyapatite. In this review several fabrication techniques of nano HAp are discussed. Suja Jose | M.
