Magnetic iron oxide (Fe3O4) powder is the pure powder form of the corresponding nanocrystals without any solvents. The well-passivated surface with organic ligands, however, prevents the nanoparticles from aggregating. The magnetic iron oxide nanocrystals from NN-Labs take advantage of the strong magnetic properties of iron oxide and incorporate them into nano-scale materials.  The iron oxide nanoparticles in powder form demonstrate excellent size distribution characteristics, which allow for their use in high-level applications where strict control over the nanocrystals’ properties and characteristics is necessary. These high-quality iron oxide nanocrystals display exceptional magnetic properties, nearing those of the pure/bulk iron oxide, and the magnetic nanoparticle powder is capable of being biofunctionalized for numerous applications.

Potential applications: magnetic fillings for composites, excellent contrast for TEM microscopy


  • Oleic acid stabilizing ligands
  • 5-30 nm particle size
