title: Ca-adsorption and apatite deposition on silk fabrics modified with phosphate polymer chains.
abstract: Silk fabric was modified with polymethacryloyloxyethylphosphate (pMOEP) by graft copolymerization. Ca-adsorption onto pMOEP-grafted silk fabric was significantly enhanced compared to that onto original silk fabric. SEM observation indicated that some crystallites were deposited on the pMOEP-grafted silk fabric after 1 week of immersion in simulated body fluid, whereas no change occurred on the surface of the original silk fabric. X-ray diffraction showed that this crystallite contained hydroxyapatite. These results indicate that pMOEP-grafted silk fabric induce hydroxyapatite formation more effectively than the original silk fabric.
