Facile preparation of assembly hydroxyapatite spheres to produce nanocomposite

AbstractThe hydroxyapatite spheres were facilely and efficiently synthesised under the cooperation of the ethylenediamine and the sodium polyacrylic acid. Owing to the electrostatic effect of the silver nanoparticles and the strong absorbability of the hydroxyapatite spherites, the two substances were combined to form special nanocomposite spheres. The nanocomposite has wide applications in medicine, environment and hygiene, etc.
