The simple method of fabrication of crystalline superparamagnetic nanoferrite (Fe3O4) particles using oxidative hydrolysis of Fe (II) salt in deep eutectic solvent-water mixture is being reported. The spectral properties of Fe3O4 nanoparticles were characterized by Fourier Transform Infrared (FTIR) spectroscopy while X-Ray diffraction (XRD) as well as scanningelectron microscopy (SEM) techniques were used to estimate the crystalline structure and particle size. The results of the studies revealed that this technique could be adopted to synthesize agglomerate-free superparamagnetic Fe3O4 nanoparticles in the simple manner in deep eutectic solvent which may find potential application in the biosensor and corrosion protective coatings.
