Methods for production and use of synthetic hydroxyapatite and fluorapatite nanorods, and superstructures assembled from the same

摘要

Disclosed herein are methods directed toward the synthesis of ordered structures of hydroxyapatite and hydroxyapatite derivatives. More specifically, disclosed herein is a method of preparing ordered hydroxyapatite nanorod structures including the steps of suspending calcium and phosphate in a solvent, adjusting the pH to above 5, and heating to a temperature sufficient to support formation of the ordered hydroxyapatite nanorod structures. In some cases, the methods may include ethylenediamine tetraacetic acid or ethylenediamine tetraacetic acid derivatives. Also disclosed are methods that additionally involve a step of coating hydroxyapatite nanorods with a protein or an amphiphile such as a surfactant or polymer.
