. The obtained iron oxide nanopowder has been used to prepare aqueous suspensions with a particle dispersion of 100–400 nm in the concentration range of 0.25–1.25 mg/L. The bioactivity of the iron oxide nanopowder has been evaluated using the pre-sowing treatment of

corn seeds. The effect of the nanopowder on the germination ability and energy of the seeds and the plant root length has been studied. The treatment with nanoparticles has been found to stimulate the development of the plant organism and make it possible to enhance germination by 15% and root mass by 23%. The quantitative iron content in different parts of the plant has been determined by atomic emission and atomic absorption spectroscopy. It has been shown that, after the treatment of the plant with iron nanoparticles, iron accumulates in the root mass with the subsequent redistribution to the leaves to stimulate the photosynthesis process.
