The specific magnetic moment of nanoparticles, depending on the content of iron oxides, varies from 90 to 180 emu/g.Ībd Elrahman AA, Mansour FR (2019) Targeted magnetic iron oxide nanoparticles: preparation, functionalization and biomedical application. The iron oxide shell protects the iron core from the external environment, preventing the rapid dissolution of Fe containing in the nanoparticles, in contrast to nanoparticles obtained in argon atmosphere. The oxygen concentration in the buffer gas has been found to determine the size of the resulting nanoparticles, their shape, and iron content. When wires are dispersed by high current electric pulse in an inert atmosphere containing less than 5% oxygen, nanoparticles with a core-shell structure are formed, where the core is α-Fe and the shell is formed by a mixture of oxides Fe 3O 4 and FeO. In the present work, a new method for the synthesis of magnetic nanoparticles based on the electric explosion of a Fe wire is proposed. Currently, as a rule, ferromagnetic iron oxide particles with a low specific magnetic moment are used for medical purposes. Magnetic nanoparticles based on iron and its oxides are promising in various biomedical applications.
