Super-paramagnetic Carbon Coated Iron Nanoparticles and Biological Magnetic Induction Heating Properties

A new kind of magnetic induction heating materials-carbon coated iron nanoparticles(CCINS) was prepared by arc method and they were used for cancer therapy. The measurement of nanomaterials revealed that they are super-paramagnetic and exhibit a very strong induction heating ability.The magnetic induction heating property was measured by the conduction by Bio-heat method. Heating effect of pig liver injection method indicates that increasing the quantity of nanoparticles used, leads to higher iron content of nanoparticles and higher temperature. Magnetic induction heating effect of the pig liver was compared in the case of filling method with the injection method. The quantity of iron nanoparticles has a significant effect on the pig temperature in the case of injection method, while it has almost no effect in the case of filling method.
