本文采用溶胶-凝胶牺牲液模板法合成了具有放射状介孔结构的球形生物活性玻璃（SBG）和具有层状介孔结构的松果体生物活性玻璃（PBG）。结果表明，以十六烷基三甲基溴化铵水溶液为模板剂，加入乙酸乙酯形成微乳液滴，氨水为模板剂腐蚀剂和水解催化剂，制备出的样品具有较好的形貌和结构。MBGs的形貌可以通过反应条件来控制。同时，通过氨水浓度可以调节MBGs的尺寸和介观结构。新型MBGs有望成为骨和牙组织再生治疗分子载体。(C)2015 Elsevier B. V.版权所有。
In this paper, two types of mesoporous bioactive glasses (MBGs) including spherical MBGs (SBG) with radial mesostructure and pineal MBGs (PBG) with lamellar mesostructure have been successfully synthesized through a novel sacrificial liquid template method in sol-gel process. The morphologies and structures of the samples were characterized and the results demonstrated that ethyl acetate was added in the hexadecy ltrimethyl ammonium bromide aqueous solution to form micro-emulsion droplets as liquid template; the aqueous ammonia was added as template corrodent and hydrolysis catalyst. The morphology of MBGs could be controlled by the reaction conditions. Meanwhile, the size and the mesostructure of MBGs could be tuned by the aqueous ammonia concentration. The novel MBGs may be a good candidate as therapeutic molecules carriers for bone and dental tissue regeneration. (C) 2015 Elsevier B.V. All rights reserved.
