Magnetic nanoparticle is one of the hot research directions in the field of nano-biomedical materials. The magnetic nanoparticles prepared by different methods and modified with different polymers are used in various fields. In this paper, we synthetically summarize its preparation methods including co-precipitation, sol-gel, microemulsion, generalize the surface modification technique with different polymers, and report the biomedical applications of magnetic nanoparticles involving target drug delivery, cell separation hyperthermic treatment for malignant cells and MRI contrast enhancement. Magnetic nanoparticles still have great potentials for development and application in the future.
