In vivo evaluation of hydroxyapatite nanocoating on polyester artificial vascular grafts and possibility as soft-tissue compatible material

The efficacy of hydroxyapatite (HAp) nanocoating on polyester vascular grafts was investigated in animal experiments. The HAp nanocrystals were covalently bonded separately between hydroxyl groups on a nanocrystal and alkoxysilyl groups in γ-methacryloxypropyl triethoxysilane graft polymerized on a
