Description
技术领域
本发明涉及药物载体领域,具体涉及一种气凝胶-水凝胶复合药物载体的制备方法及制得的载体。
背景技术
气凝胶是一种具有高孔隙率,高表面积,低密度和纳米孔结构性质的材料。通过对气凝胶孔道表面进行化学改性,气凝胶可以具有非常丰富的表面功能。气凝胶材料可应用于建筑,工业,化妆品,生物化学等诸多领域。气凝胶具有非常高的孔隙率和纳米尺寸的孔隙,其可以在孔道内负载大量的活性药物,同时可以通过表面的化学基团实现其均匀、缓慢的释放。专利号为US20020094318A1的美国专利报道了利用气凝胶作为Methadone和Methadone Hydrochloride两种药物的载体,气凝胶载体可以有效的控制药物不被过量吸收,专利号为CN102961750A的中国专利首次报道了气凝胶微粉作为药物载体的应用先例。于其机械性能非常低,气凝胶通常作为复合材料或粉末应用。
水凝胶是从一类可吸收并保留大量水的有合成或天然聚合物获得的三维网状结构物质。水凝胶具有低的界面张力、柔软、具有与生物组织结构相似的物理性质、透气性好,同时具有可控的药物释放表现。专利号是US5226902A和US6201065B1的美国专利都报道了水凝胶作为某些药物载体的应用,水凝胶是一种比较古老的药物载体,可以保护药物不受外界环境的损害,也可以通过环境的刺激的响应来实现药物的可控释放。但是水凝胶负载能力有限,负载药物类型相对单调。
