Magnetic materials directly or indirectly generate magnetic material by transition element consisting of iron, nickel, cobalt and their alloys. According to the structure of material, magnetic material can be divided into metal and alloy of magnetic materials and ferrite magnetic materials. Because of its simple preparation method, ferrite magnetic nano raw material price are low, which has a unique super Para magnetism and become the hotspot and focus of research and application. Magnetic nano materials are mainly used in magnetic resonance imaging, biological separation, drug delivery and cell markers, etc .
Magnetic nonmaterial’s have unique physical properties, such as the change of coercive force, super Para magnetism. Curie temperature drop, etc, as expect, it will be play a decisive role in new materials, energy information and the biomedical.
In practice application, particles surface of magnetic nanomaterial need be modified, to change its surface properties to meet the need of biological analysis. The surface modification of magnetic nano particles mainly have two ways: one is to rely on cooperation with chemical bonds, and use organic small molecule compounds to the decoration; the other is magnetic nanoparticles directly coating organic or inorganic materials. after the magnetic material processing it owns both magnetic and surface active group, and it can further couple with drug, antibody, protein, enzyme, cell and DNA molecular, can be used for external organs, tissues, or tumor targeting.
Application of magnetic nanoparticles in the biomedical field mainly include magnetic resonance imaging, drug delivery, separation and targeted heat treatment, etc.
