[Magnetic dipole interaction of endogenous magnetic nanoparticles with magnetoliposomes for targeted drug delivery].

Dynamics of magnetoliposomes binding to the tumor cells and the efficiency of their recognition for targeted drug delivery is largely determined by physical interaction. In this paper we assess the strength of magnetic dipole interaction that occurs between endogenous magnetic nanoparticles in tumor cells and exogenous magnetic nanoparticles as a component of magnetoliposomes, and compare it with the forces of specific binding of the antigen-antibody complex. To assess the strength of magnetic dipole interaction the model of chains of identical particles was used, and an order of magnitude, 9(-10) N, was obtained.
