Description
技术领域
本发明属于药物缓释载体和骨修复生物材料领域,具体涉及一种制备介孔二氧化硅纳米粒子/二氧化钛纳米管阵列新型复合材料的方法。
背景技术
具备良好生物学特性的内置物材料已经在骨科手术中得到了广泛应用。对于内置材料来说,良好的生物相容性是首要条件。钛和钛合金具有优秀的机械力学性能、耐腐蚀性和良好的生物相容性,被广泛应用于骨科和口腔科等。但由于其植入人体后与骨组织难以形成较为牢固的骨键合,因此仍无法完全满足临床的需要。
在钛金属内置物表面构建二氧化钛纳米管阵列,不仅可以有效提高钛金属内置物的生物相容性,促进内置物与骨界面整合,而且,由于具有独特的中空结构、纳米管径以及表面易功能化等特点,二氧化钛纳米管已成为极具吸引力的新型药物载体,广泛应用于局部药物传输体系。
介孔二氧化硅纳米粒子的大小和形状便于调控,高孔容和比表面积允许高药物负载量,灵活的平台和广阔的进一步功能化的可能性使其可以应用于靶向药物释放和控制药物释放。此外,其表面还可以进行细节处理规避不必要的生物相互作用,促进生物利用度和细胞吸收从而免于免疫系统的监督。这将实现根据需要量身定做载体的药代动力学释放曲线,提高生物利用度,实现靶向给药,从而增强治疗效果。因此,这种介孔材料被认为是制备药物载体的良好材料。

上述步骤2)的介孔二氧化硅纳米粒子的溶胶-凝胶法制备方法为:以烷基三甲基溴化铵为模板剂,正硅酸乙酯为硅源,氨水调节pH值,搅拌2~4h,过滤、干燥获得白色固体,白色固体为煅烧前的介孔二氧化硅纳米粒子,取白色固体置于马弗炉中,以1~3℃/min的升温速率升至500~600℃保温4~6h,即得煅烧后的介孔二氧化硅纳米粒子。
所述的水热反应制备二氧化钛纳米管阵列表面修饰介孔二氧化硅纳米粒子的步骤是:将阳极氧化处理后的二氧化钛纳米管阵列置于用煅烧后的介孔二氧化硅纳米粒子与水制成的分散液中,于70~100℃时下水热反应4~6h,制得二氧化钛纳米管阵列表面修饰介孔二氧化硅纳米粒子;或将阳极氧化的二氧化钛纳米管阵列置于用煅烧前的介孔二氧化硅纳米粒子与水制成的分散液中,于70~100℃时下水热反应4~6h,然后用蒸馏水淋洗获得钛基体,然后将钛基体,以1~3℃/min的升温速率升至500~600℃保温4~6h,随炉降温,即得在二氧化钛纳米管阵列表面修饰了介孔二氧化硅纳米粒子的复合材料。
上述含氟的甘油/水体系的电解质溶液采用含氟化铵0.20~0.60 wt% 的甘油/水体系的电解质溶液,所述的甘油/水体系中的甘油与水的质量比是9:1。

将5.60mmol十六烷基三甲基溴化铵溶解于122ml蒸馏水中,再加入8g 25wt%NH3·H2O,搅拌10min。边搅拌边加入10.0g 正硅酸乙酯(TEOS),再搅拌4h,过滤,蒸馏水洗,110℃下干燥12h,得到白色固体,即得为煅烧前的介孔二氧化硅纳米粒子。
称取一定量的煅烧前的介孔二氧化硅纳米粒子,加入一定量的蒸馏水配置成浓度为2.0×10-3(wt%)的分散液,将二氧化钛纳米管阵列——钛基体置于上述分散液中于85℃条件下水热反应5h,取出二氧化钛纳米管阵列——钛基体,用蒸馏水淋洗,50℃烘干,以1℃/min的升温速率升至540℃保温6h,然后随炉冷却,即得复合材料。其表面形貌如图3a所示,表面覆盖了一层介孔二氧化硅纳米粒子,从其截面的图3b可以看出,介孔二氧化硅纳米粒子已深入纳米管内部。
上述的具体实施方式是对本发明申请的进一步详细说明,但本发明权利要求保护的范围并不局限于实施方式中所描述的范围,凡采用同效变形等的技术方案,均落在本发明权利要求的保护范围。
