摘要
Hydroxyapatite has a high affinity to biological macromolecules, especially to proteins. Bovine serum proteins were extracted to be used as stablizer to prepare calcium phosphate nanoparticles . 167.7 nm and 87.7 nm particles were respectively prepared by using bovine serum protein fractions at the concentration of 0. 5 mg/mL and 1.0 mg/mL. As the polysaccharide stabilized hydroxyapatite nanoparticles, the protein-stablized nanoparticles also inhibited the proliferation rate of Bel-7402 cells. It suggested that proteins could be applied to prepare calcium phosphate nanoparticles and it also has the anticaneer effect.
