Review Article: Applications and Methods of Preparation of Iron Oxide Fe3 O4 Nanoparticle

Metal Oxide Nanoparticles are of interest in modern research and applications.  Fe₃O₄nanoparticles have interesting properties that can be manipulated in a various applications,some of these applications represent an advanced technology to biological and medical sciences  [1-5], drugs and gene mapping [6-9], Detection of proteins moieties  [10],Tumour removal  [11,12] bioanalysis  of pathogens [13],  Tissue analysis [14],monitoring of DNA structure[15,16],and Magnetic Resonance Imaging resolution improvement [18-23] chromatographic separation and purification of molecules and  biological cells [24].The purpose of this review is to summarize the different methods of preparations ofFe₃O₄ nanoparticlesand describes these methods of preparation allowing control of the size, morphology,and  surface treatment. Thesenanoparticles can be preparedby different  methods such as Gas , liquid, two-phase methods , Sol-gel methods , High pressure hydrothermal methods and Co-precipitation Method
