Magnetic hyperthermia of AFe2O4 (A = Fe, Mn, Co) nanoparticles prepared by Co-precipitation method

With 10 million deaths in 2020 cancer remains one of the most challenging diseases contemporary medicine. Chemotherapy, surgery, and radiation therapy are commonly used to treat tumors. These treatments harm healthy tissues succeed rarely advance stages cancer. Recent studies indicate that magnetic hyperthermia, which involves targeted delivery nanoparticles tumor cells followed by localized remote heating could revolutionize clinical practice treatment cancer, either as standalone intervention or adjunct radiotherapy chemotherapy. Water dispersible (MNPs) ferrites (AFe2O4; A = Fe, Mn, Co) promising candidates for hyperthermia due their high chemical stability, biocompatibility, moderate magnetization specific absorption rates (SAR). In this article, we have evaluated efficiency water based fluids AFe2O4. AFe2O4 NPs were synthesized co-precipitation method. Nanoparticles coated with a bilayer oleic acid dispersed water. Structural properties MNPs investigated X-Ray diffraction (XRD) vibrating sample magnetometer (VSM). XRD study revealed exhibits cubic inverse spinel structure. Fe3O4 (Ms 48 emu/g, Mr 2.60 Hc 49 Oe), MnFe2O4 40 35 Oe) CoFe2O4 (44 10.10 =440 soft ferromagnetic behaviour. Magnetic measurements performed function field strength (2–10 mT), frequency (162–935.6 kHz) minutes. highest SAR values mT at 935.6 kHz. Amongst tested MNPs, possess value (27.35 W/g), (1.91 W/g) (0.94 W/g). Considering this, it is concluded amongst AFe2O4, suitable applications.
