METHOD FOR OBTAINING NANOPARTICLES FE-FE₃O₄ WITH CORE-SHELL STRUCTURE AND NANOPARTICLE OBTAINED THEREBY

摘要

FIELD: chemistry.;SUBSTANCE: invention relates to a method for obtaining Fe-Fe₃O₄ nanoparticles potentially applicable as contrast agents in biomedical research. The method includes an electric explosion of an iron (Fe) wire, based on spraying the wire in a gaseous medium - a gas mixture of an inert gas and oxygen containing 1% vol. oxygen.;EFFECT: obtained are nanoparticles with an iron core-oxide shell structure with a high specific magnetic moment.;4 cl, 8 dwg, 1 tbl, 5 ex
