Calcium phosphate (CaP) includes various salts of tribasic phosphoric acid (H3PO4). H2PO4-, HPO42- or PO43- ions can all be formed through successive removal of H+ ion from this acid in the aqueous environment. Their natural occurrence in vertebrate skeletal tissues and teeth makes them of particular interest. Synthetic CaP biomaterials are well known for their use as suitable bone and teeth substitutes due to their biocompatible, bioactive, and osteoconductive characteristics. Their properties are governed by chemical composition, structure, crystallinity, and morphology. As-prepared colloidal CaP nanoparticles have been characterized using various microscopic and spectroscopic tools. Results of structural and spectroscopic data of CaP nanoparticles, as well as the effects of solution compositions, reaction conditions, chemical additives, and surfactants will be discussed in the presentation. |
