奈米磁性顆粒之製備與應用

磁性奈米微粒由於其特殊的磁性行為表現，在理論與實驗上一直深受廣泛的研究，在應用方面也被視為具有很大的發展潛力。利用化學合成法所製備的磁性奈米微粒具有大量、均一化的優點，本文將探討化學合成中其先驅物（precursor）、分散劑（dispersant）、以及溶劑（solvent）所扮演的角色。此外，我們也將針對磁性奈米微粒在磁流體、磁記錄、以及生物醫學方面的應用做一番探討。

Magnetic nanoparticles have drawn a lot of attention due to their applications and unique properties. Chemical syntheses are widely used to prepare magnetic nanoparticles with controlled particle sizes and compositions. In this paper, we will discuss the roles of precursor, dispersant, and solvent on chemical syntheses. In addition, we will introduce the applications of magnetic nanoparticles, including ferro fluids, magnetic recording, and biomedicines.
