Description

一种β-环糊精修饰的磁性纳米粒子的制备方法
技术领域
本发明涉及一种β-环糊精修饰的磁性纳米粒子的制备,具体涉及首先制备了一种核壳结构的复合纳米微球,再将β-CD修饰在其表面,获得具有一定吸附能力的磁性纳米微球的研究方法。
背景技术
过去的几十年,磁性纳米粒子已应用到很多不同领域,如传统的电学,光学,磁学等,在新领域的应用包括磁辅助生物分离与生物催化,有毒阴离子、阳离子和金属离子的吸附,如砷(V),铬(VI)和U(VI)。此外,磁性纳米粒子在磁性活体标记、细胞示踪、负载酶等生物医学领域展现出广阔的应用前景。磁性纳米粒子的应用成为目前最引人注目和最具活力的研究领域之一。众所周知,作为第二代超分子代表的环糊精(CDs)是不同数量的吡喃葡萄糖单元通过α-(1-4)糖苷键连接而成的环状低聚糖。由于环糊精中的葡萄糖单元均为椅式构象,形成了中间空洞且两端不封闭的锥筒形结构,其中,所有的伯羟基位于锥体的一侧,而所有仲羟基位于锥体的另一侧,所以环糊精的筒形结构也被称作截锥结构。因此,环糊精的外壁具有亲水性,而中心空腔是疏水、亲脂性的。由于这样的特点,环糊精可以有选择性的识别客体分子,与一些尺寸相宜的有机、无机客体分子相包合,形成超分子体系,因此在生物传感、医药材料、环境治理等领域得到广泛的应用,受到研究者们的亲睐。
当今许多工业生产面对的环境污染问题是去除污水中的染料。由于很多染料具有良好的溶解性,是常见的水污染物。其中一些偶氮类染料,一些微生物能够分解偶氮(N=N)基团,导致其形成芳香胺类产物,它们大部分是有毒的致癌物质,会影响水生生物的生存,造成严重环境问题。因此,去除工业废水中染料的方法是一个重大的挑战,现已应用的解决方法如吸附,混凝,生物降解,化学降解和光降解等。
