THE EXPEIMENTAL SETUP FOR MEASURING OF THERMAL PARAMETERS OF MAGNETIC FLUIDS IN AC MAGNETIC FIELD

摘要

Magnetic nanoparticle heating in alternating magnetic field is the novel approach to the hyperthermia technique for cancer treatment. The accurate measuring of the specific heat absorption rate of the magnetic fluid is the critical issue in the search for efficient materials to minimize the concentration of the magnetic nanoparticles in human tissues. In this work the heat absorption measurement setup consisting of a system of the magnetic field generation, a temperature measuring system, a cooling system, and an external computer control system has been developed. The results of the calibration as well as the results of measurements on the cobalt ferrite nanoparticles are presented.
