 ­Fe3O4 magnetic nanoparticles are extremely small particles that gets separated and is attracted to magnet even when in water. This is mainly due to its super paramagnetic properties. These particles are kept in about 100mL of water.  These are also non-toxic and biocompatible.

 When viewed under the foldscope, these particles show a core-shell structure which are coated with some surfactants.
