| الوصف: | In this work, a new approach for controlling the formation rate of hard tissue mineral hydroxypapatite (HAP) through the control of inner pore sizes of CaO−SiO2 bioactive material is proposed. Highly ordered mesoporous CaO−SiO2 (MCS) bioactive material with different pore sizes were synthesized through two types of surfactants, cetyltrimethyl-ammonium bromide (CTAB) and triblock copolymer EO106PO70EO106 (Pluronic F127). These two surfactants were selected for their different pore size formation tendencies, about 2.7 nm for CTAB template and 4.9 nm for F127 template. These two types of MCS materials have identical chemical composition but differ only in their pore sizes. Their bioactivities were evaluated by the incubation of the MCS in phosphate buffer solution at 37 °C for different periods of time. SEM showed that incubated MCS with 2.7-nm pore size could rapidly form a dense layer of HAP crystallites on its surfaces within a few hours, while incubated MCS with 4.9-nm pore size just formed a sparse laye... |
