Subject of research: ways to control the physical parameters of the developed nanomaterials, features of their interaction with magnetic fields, methods of control of localization and thermal action.
The regularities of the influence of the chemical composition on the magnetic properties and thermal efficiency of nanoparticles of delaphosite ferrites were investigated. Comprehensive magnetic and calorimetric studies of NaFeO2 nanoparticles and magnetic liquids based on them revealed a close connection between the magnetic characteristics of nanoparticles and the heating properties of liquids. The advantageous combination of the magnetic characteristics of the studied nanoparticles, such as the Curie temperature and the blocking temperature and the low coercive force at room temperatures, which is half the maximum amplitude of the external magnetic field used to heat the liquid, create conditions for the effective application of NaFeO2 nanoparticles in magnetic hyperthermia and remote temperature control. An approach has been developed that allows you to determine the size distribution function of nanoparticles based on the analysis of magnetic characteristics. The fruitfulness of this approach for obtaining the size distribution function of nanoparticles for AFe2O4 nanopowders (A = Ni, Zn, Co) is shown. It is shown that MPs in combination with BMNs can cause membrane shear stress and thus change the activity of mechanosensitive ion channels, which is a key point for their use in the treatment of diseases.
