Ferrite Magnetic Nanoparticles in the Design of Novel Drug Delivery Systems

Abstract

The expediency of using the method of chemical condensation as a method of synthesis of ferrite nanoparticles for their use in drag delivery systems with magnetic properties has been proved. Partial replacement of iron (II) cations of magnetite Mex2+Fe1-x2+Fe23+O4 allows carry out synthesis in one stage without additional high-temperature ferritization. The particles synthesized according to this scheme have a size of up to 20-30 nm and the high magnetic parameters. When studying the functional parameters of the synthesized ferrites, the extreme nature of the dependence of the content of the substituent cation in the structure of ferrites on its properties with a maximum at х = 0.4.
