Abstract
Ferro-Magnetic nanoparticles (Fe-MNP) have gained a lot of attention in biomedical and industrial applications due to their biocompatibility, ease of surface modification and paramagnetic properties. The basic idea of our study is whether it is possible to use glucose-conjugate Fe-MNP (Glc-Fe-MNP) for targeting and more accurate focusing in order to increase the effect of high-frequency electromagnetic fields induced hyperthermia in solid tumors. Tumors demonstrate high metabolic activity for glucose in comparison with other somatic cells.Increasing of accumulation of glucose conjugated (Glc)-Fe-MNP on tumor site and precision of radio frequency electro-magnetic field (RF–EMF) energy absorption in solid tumors, precede RF–EMF induced hyperthermia. Rat model for monitoring the early development of breast cancer. Twenty female Wistar rats (MU-line-6171) were divided into two groups of 10 rats that were either treated with N-methyl-N-nitrosourea to induce breast cancer and 10 with carrageenan to induce inflammation (control). Glc-Fe-MNP can offer a solution to increase hyperthermia effect to the desired areas in the body by accumulation and increasing local concentration due to high tissue metabolic assimilation. In this condition, it is considered that the magnetization of the nanoparticles is a single-giant magnetic moment, the sum of all the individual magnetic moments and is proportional to the concentration of Glc-Fe-MNP.
