MAGNETIC SYSTEM WITH PERMANENT MAGNETS FOR LOCALIZATION MAGNETIC NANOPARTICLES IN A GIVEN REGION OF THE BIOLOGICAL ENVIRONMENTS

The magnetic systems with permanent magnet alloy of Nd?Fe?B are discussed. The purpose of magnets is to ad-dress delivery and localization of magnetic nanoparticles in a given biological object. Features of the magnetic systems is the use of ferromagnetic pole and ferromagnetic tip, varying geometric dimensions which proved the possibility of concentration of magnetic nanoparticles in areas remote from the surface of the magnetic system. Mathematical modeling shows that change of the width of the ferromagnetic poles allows you to change both the distribution of power functions, acting on single-domain nanoparticles in height of a given volume, and value of the maximum impact force. Variation in the thickness of the magnets does not significantly influence the distribution of of power functions. The proposed magnetic systems can be used in experimental oncology.
