Nanoparticles of ferromagnetic materials and possibilities of their application in the hyperthermia of malignant tumors

Slightly agglomerated, crystalline nanoparticles of ferromagnetic compounds with spinel and perovskite La 1-x Sr x MnO 3 structure have been synthesized by the sol-gel method, precipitation from glycol solutions and using microemulsion technique. "Core/shell" La 1-x Sr x MnO 3 /SiO 2 structure have been developed. Magnetic properties of the synthesized nanoparticles have been investigated. It was shown that the obtained nanoparticles exhibit superparamagnetic properties. It has been found that the synthesized nanoparticles have promise in hyperthermia of cancer cells.
