Small organic molecule-mediated hydrothermal synthesis of hierarchical porous hydroxyapatite microspheres by the incorporation of copper ions

Abstract

Hierarchical porous hydroxyapatite (HA) microspheres with a pit in the center were prepared under the synergistic effect of small organic molecules (inositol hexakisphosphate, IP6) and copper ions. A possible mechanism for the formation of the hierarchical porous HA microspheres is proposed.
