Magnetic nanoparticles, in particular iron oxide nanoparticles, have been extensively studied due to their characteristics and applications in information storage and medicine. Their inherent properties were determined by their size, shape, composition and crystallinity. When particle size Fe2O3 or Fe3O4 decreased to nano scale, it showed paramagnetic behavior. In nanotechnology biotechnology, with the introduction of polyethylene glycol, the biocompatibility of nanoparticles was greatly improved, and the polyethylene glycol attachment increased water solubility, reduced toxic effects, reduced enzymatic degradation, and increased half-life of the molecule. Polyethylene glycol was often used as a soft molding for long-chain, single-dimensional nanostructures with selective absorption in the desired areas (by increasing the absorbance of polyethylene glycol by magnetic nanoparticles of circulation time in the blood stream). Correction of nanoparticles with polyethylene glycol has been used to resist protein uptake and facilitated the absorption of nanoparticles at cancer time to determine cancer cells. The control of the size of the iron oxide magnetic nanoparticles was prepared and prepared by an instant solvent method using a combination of sodium dodecyl sulfate and polyethylene glycol surfactant as protective reagents by Liu et al. A mixture of sodium dodecyl sulfate and polyethylene glycol was studied as a protective reaction and sodium dodecyl sulfate and polyethylene glycol alone.
