Nanotechnology deals with engineering and creating new materials in the dimension of up to 100 nm that can have new and unique physical or chemical properties differ significantly from the bulk materials. This revolutionary technology is already applied in many fields and it is expected to be dominant in numerous industrial processes. One of the most interesting classes of materials that nanotechnology deals with belongs to nanoparticles possessing magnetic properties. Magnetic nanoparticles (MNP) such as iron oxides are investigated intensively during the last two decades in different aspects: preparation, physical properties and applications. Several methods are utilized to prepare magnetic nanoparticles with different morphologies that can affect their properties. These methods include thermal decomposition of organic precursors in organic solvent, microemulsion route, reduction of metallic salts in polyols, spray and laser pyrolysis and co-precipitation in aqueous media. Magnetic nanoparticles can interact with external magnetic field, which facilitate their separation and direct their transport. This is very interesting property of these materials that leads to different applications in various fields. Indeed, magnetic nanoparticles are utilized for biomedical applications such as drug delivery, magnetic resonance imaging, biomolecular sensors, bioseparations, and magneto-thermal therapy. In addition, magnetic nanoparticles are now used widely in organic synthesis as excellent supports for catalysts. The supporting of catalysts on the surface of magnetic nanoparticles can lead to effective, selective and easily separable catalysts. The special issue of the journal Applied Sciences aims to cover recent advances in the investigation of magnetic nanoparticles and their applications.
