Catalase-like activity properties of Fe3O4/PVP nanoparticles in the study of sorghum seed germination processes

Abstract

Since the discovery of the effect of the behavior of ferromagnetic (Fe3O4) nanoparticles in 2007 by a group of researchers, nanoparticles have shown their own peroxidase-like and catalase-like activity. A cycle of articles, dedicated to similar properties for other nanoparticles, have appeared: CeO2, Ru, Pd, NiO. However, nanomaterials with catalase-like activity have rarely been studied. In particular, depending on the acidity of the medium, magnetite nanoparticles as enzyme mimetics can exhibit both peroxidase and catalase properties.
