纳米Fe3O4磁性颗粒表面改性及其在医学和环保领域的应用

纳米Fe₃O₄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Fe₃O₄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Fe₃O₄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Fe₃O₄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。

Surface modification and application in biomedicine and environmental protection of magnetic Fe3O4 nanoparticles

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.
