Biomedical Application of Magnetic Nanoparticles principles and Current Developments

摘要

Magnetic nanoparticles have been utilized for biomedical purpose due to their unique features such as its superparamagnetism, high saturation magnetization and high effective surface areas, etc. In diagnosis aspect, magnetic nanoparticles can be used as contrast agents for magnetic resonance imaging, and as labels for biomedical sensing. On the other hand, they have attracted attention in disease therapies because of their potential as carriers for site-specific drug delivery and heating mediators for hyperthermia. However, the bio-separation is also an important in vitro application of magnetic nanoparticles. In this article, the development of variety of biomedical application including biomedical diagnosis imaging, disease therapies, bio-separation and biosensing were introduced.
