PEG-NH2-Fe3O4 20nm(4Mg/ml)

Fe3O4 is an inorganic substance with the chemical formula Fe3O4. It is a black crystal with magnetism, so it is also called magnetic iron oxide. It is regarded as a compound composed of ferrous oxide and ferric oxide (FeO · Fe2O3). This substance is insoluble in water, alkali solution, ethanol and other organic solvents. The natural ferric oxide is insoluble in acid solution, and it is easy to oxidize into ferric oxide (Fe2O3) in the air under humid conditions.
