Outline of Final Research Achievements

We have predicted that novel dissipative structures of magnetic nanoparticles are formed during hyperthermia treatment. For verifying this finding, we have prepared monodisperse magnetite nanoparticles and observed small angle scattering of the nanoparticles in the large alternating magnetic field. The knowledge obtained here sheds new light on the design of targeted magnetic hyperthermia treatments.
