Аннотация: Iron oxide magnetic nanoparticles are widely present in various natural systems including living organisms of all levels and types of organization - bacteria, plants, insects, fish, birds, animals and human, etc. Biogenic generation of nano-phase magnetic oxides is connected with important physiological processes including a number of pathologies, in particularly, human neurodegenerative diseases. In that connection, the investigation of mechanisms of formation of iron oxide nanoparticles in living systems is important from fundamental viewpoint and also is necessary for development of novel efficient methods and means for diagnostics, therapy, ecological monitoring, etc. Using EMR and TEM techniques we have demonstrated and studied the formation of ordered quasi-linear arrays of iron oxide nanoparticles in immobilized DNA complexes via biomimetic reactions involving only biogenic compounds (ferritin and ascorbic acid) in aqueous solutions under normal conditions. The effect of photoinduced generation of magnetic nanoparticles in suspension of thylakoids of spinach chloroplasts was discovered. Also, the appearance of EMR signal characteristic for magnetic nanoparticles was found in various plants as a result of effects of a number of external stress factors.
