Calcium phosphate (CaP) includes various salts of both calcium ion (Ca2+) and tribasic phosphoric acid (H3PO4). 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. Here we are developing synthetic methods of chemically functionalized colloidal CaP nanoparticles in a non-aqueous solvent such as ethanol. We demonstrate that CaP nanoparticles can be functionalized with various surfactants of which the main function is to stabilize the nanoparticles. 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. |
