Abstract: This work aims to establish and to optimize the conditions for chemical synthesis of nanosized magnetic core-shell iron oxide. The core is magnetite and for the shell we used gold in order to obtain different nanoparticles. Iron oxides was synthesized by sonochemical process using ferrous salts, favoring the synthesis at low-temperature, low costs, high material purity and nanostructure control. After synthesis, some investigation techniques as: X-ray diffraction (XRD), atomic force microscopy (AFM), Termogravimetric analysis (TGA), Fourier-Transform Infrared Spectroscopy (FTIR) and UVVis absorbance spectroscopy, have been used to see the characteristics of the nanoparticles. For invitro applications, it is important to prevent any aggregation of the nanoparticles, and may also enable efficient excretion and protection of the cells from toxicity. For biomedical applications like magnetic biofunctional material vectors to target tissues, the particles obtained have to be spherical with 10 nm average diameter.
Keywords: magnetite, nanocomposite, core-shell, sonochemical method
