| 摘要 |
The invention concerns colloidal dispersions of calcium phosphate nanoparticles and at least one protein, the size of said nanoparticles ranging between 50 and 300 nm, and the morphology of said nanoparticles being spherical. Said dispersions are prepared by a method characterized in that it comprises the following steps: forming a mixture comprising the calcium complexing agent and a calcium source, then adding to said medium at least one protein, thereafter adding thereto a phosphorus source and heating the medium. The invention also concerns nanoparticles obtained by freeze-drying said dispersion, and the particles obtained by calcining the freeze-dried nanoparticles. The invention can be used in the food, cosmetic, pharmacological industries. |
