Mussel-Inspired Multifunctional Surface through Promoting Osteogenesis and Inhibiting Osteoclastogenesis to Facilitate Bone Regeneration

Through a facile surface coating process, mussel-inspired polydopamine was adhered to the surface of a biocompatible porous scaffold followed by the immobilization of a small-molecule activator and the subsequent in situ coprecipitation of hydroxyapatite nanocrystals.
