This study refers to the novel hyperthermia application of poloxamer-coated cobalt ferrite as a new approach for thermal eradication of DU-145 human prostate cancerous cells under a radio frequency magnetic field (RF-MF) . The hydrothermal method was applied for the synthesis of cobalt ferrite nanoparticles. Then, the structure, size, and morphology of nanoparticle were characterized. The cytotoxicity of the synthesized nanoparticles and RF-MF exposure on DU-145 prostate cancer cells was investigated separately or in combination with colony formation methods and MTT [3-(4,5-Dimethylthiazol-2-yl)-2,5-Diphenyltetrazolium Bromide] assay. Transmission electron microscopy (TEM) confirmed the spherical morphology of nanoparticles with a size of 5.5 Æ 2.6nm. The temperature of cells treated with nanoparticles under RF-MF reached 42.73 Æ 0.2°C after 15min. RF-MF treatment or nanoparticles have not affected cell viability significantly. However, the combination of them eradicated 53% Æ 4% of cancerous cells. In-vitro hyperthermia was performed on human prostate cancer cells (DU-145) with cobalt ferrite nanoparticles at specific concentrations that demonstrated a decrease in survival fraction based on colony formation assay compared to cells that were treated alone with nanoparticles or with RF-MF.  \n1. Introduction  \nEradicating cancer cells without harming healthy cells has been a primary aim in chemotherapy and radiation therapy. The side effect of chemotherapy and radiation treatment on normal tissue, multidrug resistance and radiation resistance, problems in biological issues to concentrate chemotherapy and radiation treatment of some tumors, etc. have reduced the treatment efficiency of prostate cancer [1] . It has been demonstrated that hyperthermia could enhance the chemoor radiation treatment of PCa [2] . Historically, heat has been transferred to cancerous cells using external applicators, either in the form of ultrasound, electric field, or microwaves [3] . However, energy generated by these methods creates unwanted hotspots in normal tissue because it is difficult  \nto focus the energy on the target area [4] . As a result, thereis a continuing need for new hyperthermia application techniques with better heating properties [5] . Therefore, new approaches must be developed to supplement or replace existing procedures of treatment. Nowadays, there are various modern techniques based on nanoparticles that show fewer side effects, hyperthermia induced by an external magnetic field (magnetic hyperthermia (MH)) is an example of them [5, 6] .
