Preparation and characterization of magnetic nanoparticles with chitosan coating

Magnetic chitosan nanoparticles were prepared by the suspension cross-linking technique for use in the application of magnetic carrier technology. The Fe₃O₄ magnetic nanoparticles were synthesized by co-precipitation of FeCl₂ and FeCl₃ solution in base medium for using in the preparation of the magnetic chitosan. The morphological and magnetic properties of the magnetic nanoparticles were characterized by different techniques (TEM, XRD, VSM, FTIR, etc.). The magnetic properties of chitosan – magnetic nanoparticles were analyzed by VSM, and M_S around 15 emu/g.
