| 英文摘要: |
| Fe3O4 magnetic nanoparticles have been widely applied to various fields because of its excellent magnetic properties.
Especially in biomedical domain, the nanoparticles had attracted more and more attention. Because of the excellent superparamagnetic
properties they have, Fe3O4 nanoparticles have been widely applied to various fields: It can be used as contrast agents, which will enhance
the contrast and imaging effect of MRI and can be incorporated into the nano-targeted drug delivery systems for drug delivery. Besides, it
can be embedded into the proteins for magnetic separation and can be used in gene therapy, which can raise the transfection efficiency of
target cells. Meanwhile, it can be used for hyperthermia of cancer due to the good effect of light-heat conversion subjected to near-infared
light, where the temperature rise, showing fine results. The objective of this review is to systematically summarized the applications of
Fe3O4 magnetic nanoparticles in biomedical field as drug targeted delivery, protein magnetic separation, magnetic resonance imaging, hyperthermia,
as well as gene therapy vectors, and so on. And described the foundation and advantages in biomedical field. |
