Ferromagnetic Nanopowder Iron-Based Materials Synthesized from Iron Citrates for Medical Purposes
0569–0576 (2022)
PACS numbers: 61.05.cp, 68.37.Hk, 75.50.Tt, 75.60.Ej, 81.07.Wx, 81.40.Rs, 87.85.Rs
In recent years, magnetic composite nanosize powder materials are increasingly used in medicine as a magnetic base for the transfer of a number of drugs. The undoubted advantage of using such composite medical systems is the maintenance of an appropriate level of local concentrations of therapeutic drugs in the affected area under conditions of a significant reduction in the volume of their total dosage and a reduction in side effects on the human body as a whole. As established, the method of low-temperature (350–400°C) decomposition/reduction of citrate salts in hydrogen medium allows obtaining nanosize ferromagnetic α-Fe powder with a specific surface area of 31.4 m2/g. High specific surface area and magnetic characteristics allow us to recommend ferromagnetic α-Fe powder as a magnetic base for the development of composite medical materials.
Key words: ferromagnetic nanopowders, magnetic nanosize powder materials, composite medical systems, biologically active agents.
