Microwave-assisted hydrothermal rapid synthesis of hydroxyapatite nanowires using adenosine 5′-triphosphate disodium salt as phosphorus source

Hydroxyapatite (HAP) is the most important inorganic constituent of biological hard tissues such as bone and tooth. However, the simple and controllable fabrication of HAP one-dimensional nanostructures remains a challenge. Herein, we report a microwave-assisted hydrothermal method for the rapid preparation of HAP nanowires using CaCl2 center dot 2H(2)O and adenosine 5'-triphosphate disodium salt hydrate (Na(2)ATP) in aqueous solution without any surfactant. The effects of the reaction temperature and time on the morphology of the product are investigated. This method does not need any hard template or surfactant, avoiding the procedures and cost for their removal in the product. The asprepared products are characterized by X-ray powder diffraction (XRD). Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM) and transmission electron microscopy (TEM). (c) 2012 Elsevier B.V. All rights reserved.
