  • Method of manufacturing hydroxyapatite and uses therefor in delivery of nucleic acids
    Patent number: 7776600
    Abstract: Provided is a method for production of nanocrystalline hydroxyapatite particles, and nanocrystalline hydroxyapatite particles produced according to the method. The nanocrystalline hydroxyapatite particles exhibit substantially superior cell transformation abilities as compared to known and commercially-available calcium phosphate kits. The nanocrystalline hydroxyapatite particles also find use in tissue engineering applications, for example bone and tooth engineering and repair applications.
