Ferromagnetic or ferromagnetic substances undergo a second-order transition into paramagnetic compounds above the Curie temperature. Fe3O4’s Curie Temperature is 585.
Nano-ferrosoferric (Fe3O4) oxide powder is magnetic. It can move in a directional manner when exposed to an external magnetic field. Its particles are superparamagnetic within a specific range and it can produce heat under the influence of an external alternating magnetic field. It is widely used because its chemical properties are stable.
Magnetic Nanoparticles/Magnetic Nanoparticles (MNPs) are new materials with rapid development and high application value in recent years. The application of magnetic nanoparticles has increased in recent years.
The nano-sized ferro-ferric oxide Fe3O4 exhibits special magnetic properties that are not found in bulk materials. These properties are due to the Nano-particles’ small size effect as well as their surface effect. This makes it a very useful material in industries, biomedicine and other fields.
In biomedicine, nano-Ferrosoferricoxide Fe3O4 has many applications.
Magnetic polymer nanospheres (also called immune magnet microspheres), is composed of magnetic particles and polymer scaffolds for the preparation of biomedical material. The polymer materials used include silanes, polyethylenes, polystyrenes, polyacrylic acids (starch, dextrins, gelatins, albumins, ethylcelluloses, etc.). Skeleton materials are mostly inorganic with magnetic.
Fe3O4 has good material properties. It is biocompatible, strong, non-toxic, and can be used for a variety of biomedical applications, including magnetic separation technology, tumor heat treatment, cell markers, and magnetic resonance imaging. The magnetic hyperthermia treatment is a hotspot for domestic research, particularly in the treatment and prevention of cancer-related drug carriers.
