A new study shows that the reproducible magnetization patterns of magnetite is preferentially partitioned in the human brain, specifically in the cerebellum and brain stem. In 1992 researchers identified the presence of magnetite—a permanently magnetic form of iron oxide—in human brain tissue. Iron in the body was no surprise.

Jan 28, 2012· • Magnetite has the chemical formula of FeO·Fe2O3 or Fe3O4. Chemical formula of hematite is Fe2O3. • Magnetite iron is in +2 and +3 oxidation states whereas, in hematite, it is only in +3 oxidation state. • Magnetite has higher iron content than hematite; therefore, its quality is higher.

organosilanecoated magnetite exhibited superparamagnetic behavior and strong magnetization at room temperature. Basic groups anchored on the external surface of the coated magnetite were observed. The superparamagnetic particles of coated magnetite are able to bind to biological molecules, drugs and metals and in this way remove them from
