Hydrophobic and Hydrophilic Magnetite Nanoparticles: Synthesis by Chemical Coprecipitation and Physico-Chemical Characterization

Abstract

The building blocks for the fabrication of biocompatible magnetoresponsive carriers are the subdomain magnetite nanoparticles surface coated by biocompatible molecular layers which ensure their stabilization and dispersion in an appropriate carrier liquid, in order to obtain stable magnetic nanofluids that are the primary materials for the envisaged magnetic nanocomposites. The synthesis by chemical coprecipitation is the most simple and cost effective route to obtain hydrophobic and hydrophilic magnetite nanoparticles at industrial scale. Manifold physico-chemical characterization of the magnetic nanofluids is employed in order to certify their requested composition and structure.
