The generation of biogenic magnetic nanoparticles in living systems (leaves of various plants, grape snails and laboratory rats) was studied by electron paramagnetic resonance (EPR) and Transmission Electron Microscopy (TEM) methods [1,2,3]. Under the influence of stress factors as a result of the phenomenon of biomineralization, the appearance of magnetic properties was determined in them [4,5]. Thus, it was determined that new paramagnetic centers related to iron oxide nanophase particles were registered in a wide range of magnetic fields under the influence of stress factors in the research objects.

The results obtained were confirmed in TEM experiments, and the resulting magnetic nanoparticles could be observed visually.
