The presence and localization of biological magnetic nanoparticles in various organs and cells were investigated using atomic force, magnetic force microscopy and genetic analysis. Separate BMNs and chains of the mitral valve in aneurysm of the heart and aneurysm of the human aorta were determined. Also among the bacteria and pathogens, the potential producers of BMD were found. The expediency of using the methods of comparative genomics for the separation of microorganisms with magnetic properties and the selection of a more efficient method of neutralizing magnetic hyperthermia has been shown. It has been shown that the forces of dipole-dipole interactions between amorphous magnetic and artificial magnetic nanoparticles are sufficient to detect S. aureus and further neutralize them by magnetic hyperthermia. Effect of shell thickness on DC magnetic parameters (saturation magnetization, coercivity, blocking temperature) and AC losses (specific loss power, intrinsic loss power) has been studied for Fe3O4/CoFe2O4 core/shell-like magnetic nanoparticles. It is concluded that the employment of core/shell-like architecture paves the way to tune and optimize the parameters of spinel ferrite nanoparticles. The superparamagnetic β-NaFeO2 nanoparticles were studied and their morphological parameters, colloidal stability, and optimal fields for induction heating at magnetic hyperthermia were determined. In the study of cytotoxicity in vitro, the dose value of the synthesized β-NaFeO nanoparticles at which observing a decrease in the viability of HeLa cancer cells was determined.
