Abstract
In this study, combining magnetic nanoparticles with halloysite nanotubes (HNTs), Fe3O4/ HNTs nanocomposites were synthesized using the co-precipitation method. The synthesized nanocomposites were characterized by scanning electron microscopy (SEM), X-ray diffraction (XRD), Fourier transform infrared (FTIR), Thermogravimetric analysis (TGA), energy-dispersive Xray (EDX) analysis, vibrating sample magnetometer (VSM). At room temperature, the saturation magnetization (MS) showed that Fe3O4 and Fe3O4/ HNTs nanoparticles have a magnetic saturation of 73.84 emu/g and 30.63 emu/g, respectively. The maximum specific absorption rates (SARs) obtained for Fe3O4/ HNTs nanocomposites were 94 w/g at a frequency of 400 kHz and 53 w/g at a frequency of 200 kHz, respectively. The results show that Fe3O4/ HNTs nanocomposites are desirable in the application of hyperthermia to treat cancer.
