Abstract:
Ferrite nanoparticles (NPs) have potential biomedical applications due to their heat-generating capability when they are subjected to AC magnetic field. Achieving hyperthermia-efficient ferrofluids is an outstanding challenge. Thus, in this study bare and Triethylene glycol coated CoFe2O4 NPs were obtained through the co-precipitation method. The structural properties and morphology of the samples were studied through X-ray diffraction and electron microscopy images. The results showed that lattice parameters are not changed by polymer coating, but the morphology of the powders is affected, and the aggregation of NPs decreases in the coated sample when compared with the bare one. The effect of the polymer coating on specific absorption rate (SAR) values of the NPs was studied. The results revealed that SAR value of the coated NPs is greater than that of bare NPs, indicating the coated ones to be more appropriate for hyperthermia applications, which is due to the low aggregation of coated NPs as a consequence of polymer coating.
