摘要：
Using high intensity ultrasonic irradiation, we prepared calcium phosphate-albumin colloidal particles from aqueous solutions of Ca(H2PO4)(2) and Ca(OH)(2) in the presence of bovine serum albumin (BSA). The effect of concentration of BSA (2-5 g/L) properties of the colloidal particles was studied at constant temperature. The effect of a resting period on the size distribution of the colloidal particles was also investigated. Morphology, phase composition, average diameter, size distribution and zeta potential were obtained by transmission electron microscopy, X-ray diffraction, particle size determination by PCS and electrokinetic measurements.
