Iron Oxide nanoparticles in their magnetite crystal form (Fe3O4) are the most explored magnetic nanoparticles, due to their extensive application within catalysis, biomedicine, photonic crystals, microfluidics, data storage, environmental remediation and optical filters,
We at Particular Materials synthesize nano magnetic Fe3O4 and we produce dispersions with excellent stability, monodispersity and fully disaggregated state.
Our Iron oxide Fe3O4 nanoparticles portfolio consist of magnetite (Fe3O4) particles with diameters ranging from 4 to 70 nanometer and find applications in several industries.
Magnetic NPs, with sizes between 2 and 20 nm display superparamagnetism, i.e. their magnetization is zero, in the absence of an external magnetic field and they can be magnetized by an external magnetic source. This property provides additional stability for magnetic nanoparticles in solutions.
In order to be able to take advantage of the various properties of iron oxide (Fe3O4) nanoparticles, significant care needs to be taken in controlling size, monodispersity and crystalline structure.
We at Particular Materials synthesize nano magnetic Fe3O4 and we produce dispersions with excellent stability, monodispersity, crystalline purity and fully disaggregated state.
