Metal nanoparticles have the potential to be used in many technological and medical applications, especially in imaging, diagnosis, and treatment. Most of the metal nanoparticles are cytotoxic. Coating of metal nanoparticles with inorganic / organic groups is proposed to reduce their toxicity. In our research, Fe3O4 nanoparticles were produced by the co-precipitation method and separately coated with tetraethyl orthosilicate (TEOS), polyethylene glycol (PEG) and chitosan molecules in order to reduce their cytotoxicity where core@shell magnetic nanostructures were obtained. For the chemical characterization of the coated magnetic nanoparticles, Fouirer Transform Infrared (FTIR) spectra were taken, and thermal gravimetric analysis (TGA) were performed. Morphological features were characterized by Transmission Electron Microscopy (TEM), and Magnetic Hysteresis Measurement (VSM) analysis were performed for magnetic measurements.
