Abstract
A novel one-step preparation of magnesium particles and Pluronic F127 incorporated with calcium sulfate hemihydrate (CSH) and nano-hydroxyapatite (nHA) ready to use injectable or moldable beads was developed for bone tissue regeneration applications. The nanocomposite showed setting time less than 15 min, very good injectability (75-85%) and good mechanical strength (52-80 MPa). Samples immersed in SBF showed controlled degradation (40-45% reduction in weight) in 28 days. The nanocomposite bone graft was cytocompatible against MG63 osteosarcoma cells and increased the osteogenic gene expression by 2-3 folds. These results indicate that it can be a potential defect filling biomaterial for bone tissue regeneration at the fracture site.
