Abnormal cell proliferation and the body's inability to resolve this problem can lead to cancer. Common methods of cancer treatment have side effects. The use of magnetic nanoparticles under a magnetic field is a promising approach in the treatment of cancer. When magnetic nanoparticles are placed in an alternating magnetic field, the fro fluid transfers heat energy and reaches equilibrium. The effective mechanisms for generating heat in hypothermia are Neel's and Brownian's relaxation. The specific absorption rate is one of the most important parameters in the design of magnetic nanoparticles for heat therapy. At present, the calorimetric method is used to determine the specific absorption rate of nanoparticles. Tumor warming can cause serious damage to surrounding healthy cells. On the other hand, if the temperature rise is not high enough, the desired treatment can not be achieved. In this paper, we have used a colorimetric method to measure the specific adsorption rate for three nanoparticles of Fe3O4, NiFe2O4, and CoFe2O4.
