β-环糊精/四氧化三铁纳米复合材料功能化研究进展

Progress in the Functionalization of β-Cyclodextrin/Fe_3O_4 Nanocomposites

四氧化三铁纳米粒子具有顺磁性、高比表面积和能锚定和吸附功能分子的活跃表面等性质,在诸多领域显示了广泛的应用价值。将环糊精修饰在纳米四氧化三铁上,构筑成为β-环糊精/四氧化三铁纳米复合材料,既充分发挥环糊精在主客体催化、药物负载和缓释、有机污染物的包合作用,又能巧妙利用了纳米四氧化三铁比表面积大,单分散性和磁性响应可回收的优势。文章综述了β-环糊精/四氧化三铁纳米复合材料在环境污染物吸附/相分离、催化、药物载体等方面的研究进展。

Fe 3 O 4 nanoparticles with paramagnetism,high specific surface area,active surface for immobilization or adsorption of functional molecules have been widely used in many fields.The cyclodextrins were modified on nano-ferric oxide to formβ-cyclodextrin/Fe 3 O 4 nano-composite.It not only gives full play to the cointegration of cyclodextrin in host and guest catalysis,drug carrier and release,organic pollutants,but also makes use of the advantages of nano-ferric oxide with large specific surface area,single dispersity and magnetic response recovery.In this paper,the research progress on the adsorption/phase separation,catalysis and drug delivery of theβ-cyclodextrin/Fe 3 O 4 nano-composite was reviewed.
