摘要/描述

pitation from the 4 mM solution within the vesicles was amorphous calcium phosphate (ACp) and it remained stable at room temperature. The ACp was transformed into HAp crystals after treatment in hot water bath (60℃) for 24 h. As for the 0.03 mMsolution, which is nearly the critical saturation concentration of HAp, the precipitated crystals were small HAp. The role of the vesicle membrane in the controlled precipitation of calcium phosphate is discussed in terms of kinetic and spatial restrictions inherent in the reaction environment. The influence of concentration of calcium ion is also discussed.
