Abstract

Magnetophoretic and optical methods combined with pulsating weak magnetic field 1-10 Hz were applied to observe resonant vibrations of biological microparticles with anisotropic magnetic properties. Modeling of oxidative disorders in tissues was realized using reactive oxygen species (ROS) initiation and ferritin incorporation into porous sorbent beads and blood cells. Microscopic video recording of cells in high gradient magnetic separation allowed to determinate changes of magnetic moments under stress activating influences.
