Magnetic nanocomposite based on maghemite nanoparticles and a natural polysaccharide, sodium alginate, is synthesized. Nanocomposite is characterized by spectrophotometry, transmission electron microscopy, X‐ray diffraction, and dynamic light scattering. The obtained composite demonstrates the high aggregative stability. An external magnetic field causes the nanocomposites to move in an aqueous dispersion.
