摘要：

Synthetic calcium phosphate (CaP) has been investigated as promising biomaterial due to its excellent biocompatibility. CaP nanosheet-assembled microspheres were prepared using Ca(CH3COO)(2), NaH2PO4 center dot 2H(2)O and PLA-mPEG in aqueous solution by microwave-assisted hydrothermal method at 120 degrees C for 30 min. Meanwhile, CaP polyhedral were prepared using Ca(CH3COO)(2), NaH2PO4 center dot 2H(2)O and PLA-mPEG in mixed solvent of water and ethylene glycol (EG) by microwave-assisted solvothermal method at 120 degrees C for 30 mm The products were characterized with X-ray powder diffraction (XRD), transmission electron microscope (TEM), scanning electron microscope (SEM) and thermogravimetric analysis (TG). EG showed a significant effect on the chemical composition and morphology of the product. The hemoglobin protein adsorption properties of the as-prepared products were investigated. The Hb adsorption amount increased with increasing Hb initial concentration, and were decreased with increasing volume of EG.
