  • Patent number: 8691882
    Abstract: Provided are an organic-inorganic hybrid scaffold with surface-immobilized nano-hydroxyapatite, and a method for the fabrication thereof. The scaffold is fabricated by reacting an acid group present on a surface of nano-hydroxyapatite with a primary amine present on a surface of a polymer support in the presence of EDC (1-ethyl-3-dimethylaminopropyl carbodiimide) to immobilize nano-hydroxyapatite onto the surface of the polymer support. The surface of nano-hydroxyapatite is previously grafted with poly(ethylene glycol methacrylate phosphate) (PolyEGMP) having phosphonic acid functionality or with a polymer having carboxylic acid functionality.
