EN Syntheses and characterization of two types of systems of magnetic nanoparticles functionalized with biocompatible molecules have been presented. Two colloidal suspensions of iron oxide nanoparticles fabricated by the same co-precipitation method were obtained; the nanoparticles with perchloric acid (HClO4) and with citric acid (C6H8O7), were coated and dispersed in water. The structure at nanometric level of functionalized magnetic nanoparticles was analyzed, using data obtained from magnetic, rheological and structural measurements. Magnetic properties were discussed based on magnetization measurements. Fourier transform infrared absorption spectra have been recorded to obtain additional information on the composition of functionalized magnetic nanoparticles. To assess the optical properties of highly diluted suspensions, UV-VIS absorbance spectra were recorded. Light scattering anisotropy on functionalized magnetic nanoparticles was investigated as well. The dimensional distribution of the nanoparticles physical diameter was comparatively presented using the box-plot statistical method applied to the data provided by transmission electron microscopy.
