This is the outcome of intense research and it involves the method for preparing nanostructured zinc doped hydroxy apatite. The research involves the preparation of nanorods of zinc doped hydroxyapatite by subsequent mixing of metal nitrates and organic fuel. The chemical and physical properties of biomaterials are related to their size and shape. This is essential in the treatment of fractured bones, degenerated bones, bone deformities, degenerated spines, dental corrosion and disorders.
