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

摘要

Slightly agglomerated, crystalline nanoparticles of ferromagnetic compounds with spinel and perovskite La1−xSrxMnO3 structure have been synthesized by the sol-gel method, precipitation from glycol solutions and using microemulsion technique. “Core/shell” La1−xSrxMnO3/SiO2 stucture 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.
