纳米Fe_3O_4磁性颗粒表面改性及其在医学和环保领域的应用

Surface modification and application in biomedicine and environmental protection of magnetic Fe_3O_4 nanoparticles

纳米Fe_3O_4磁性材料在生物医学、环保、催化及电子信息等领域有巨大的应用潜力,但单独的纳米Fe_3O_4颗粒存在一些弊端,难以直接使用,在生物医药领域尤其如此。对Fe_3O_4磁性纳米粒子进行表面改性,可以改善其结构与性能,因此,备受科学界关注。对近年来Fe_3O_4磁性纳米颗粒的表面改性方法及其在生物医学、环境工程两大领域中的应用做了综述,并对今后发展趋势做了初步的展望。

In recent years, Fe3O4 magnetic nanoparticles have been widely explored in the fields of biomedicine, environmental protection, catalysis and electronic information. However, some drawbacks for bare Fe3O4 particles have limited their applications, especially in the field of biomedicine. To tackle this issue, the surface modification of Fe3O4 magnetic nanoparticles has been widely explored. This paper has reviewed the surface modification methods of Fe3O4 magnetic nanoparticles and their applications in biomedicine and environment. The future research trend and perspective of Fe3O4 magnetic nanoparticles are also briefly outlined.
