Abstract
This work was done to emphasize the cancer treatment using different methods such as: radiotherapy, and hyperthermia (microwave and induction circuit). Also, these methods enhanced by magnetic nanoparticles were tested. The thesis illustrated that radiotherapy method showed the best performance in treating cancer. Although Enhancement of these methods using Magnetic nanoparticles were also studied, but there was a fairly noticeable performance increase. Before and after treatment the tumor size was measured using vivo method. The Tumor size decreased after exposing the mice for 30 Gy for 15 minutes using artiste linear accelerator. The iron oxide nanoparticles were prepared by co-precipitation method, at room temperature by stirring for 10 minutes. Different molar ratios of FeCl2 and FeCl3 were used. All the prepared samples were characterized by TEM and XRD.
TEM confirmed all the prepared iron oxide samples were nanoparticles with diameter range between 5-12 nm. XRD analysis assured that the prepared samples were poly crystalline in comparable with literature review. XRD pattern result showed that the presence of the most intense peak corresponds to the (311) crystallographic orientation of the spinel phase of Fe3O4 magnetic nanoparticles. The mean size of the nanoparticles was determined from the X-ray diffraction pattern by using the Scherrer approximation. The magnetization of the nanoparticles was detected by its attraction to a simple magnet.
