superparamagnetic Fe3O4 nanoparticles 30-50 nm

SPIONs(Fe3O4 NPs),Nano Fe3O4 particles are a functional material that exhibits many special functions in magnetic recording materials,magnetic fluids,and other fields.In superparamagnetism, nanoparticles exhibit behavior similar to magnetic moments,but their magnetic moments rapidly reverse under the influence of an external magnetic field, rather than maintaining a stable magnetization direction under a magnetic field like conventional paramagnetic materials.This product is only for scientific research and cannot be used on the human body.
