In this paper, investigations concerned with the study of magnetic properties of polyfunctional nanocomposites (NC) of a core–shell type for wide functional destination, which are synthesized on the base of superparamagnetic nanosize single-domain nanoparticles (NP) of different chemical nature, are reviewed. In the ideological plan, the research is aimed onto developing the concept of creating magnetically sensitive NCs with multilevel hierarchical nanoscale architecture and functions of nanorobots. As shown, the usage of both the ensemble of superparamagnetic carriers as a probe and the Langevin paramagnetism theory can determine the size parameters of the complex shell structure of multilevel nanocomposites and optimize them. The obtained results are used in creating the newest magnetically sensitive adsorption materials for technical, environmental, and medical applications, for development and standardization of new forms of magnetogoverned medicinal agents with targeted delivery, for combined local therapy and diagnostics as well as for control of size parameters of nanostructures in the process of their fabrication.
Key words: magnetic properties, single-domain superparamagnetic nanoparticles, polyfunctional nanocomposites, multilevel hierarchical nanoarchitecture of a core–shell type, superparamagnetic probe, size parameters.
