title: Specific absorption rate of magnetite nanoparticle powders with and without surrounding organic ligands.
abstract: Magnetite nanoparticles have been synthesized at different temperatures in order to get nanoparticles of different average sizes. Powders of the synthesized nanoparticles were introduced in a radio frequency electromagnetic apparatus built to perform hyperthermia measurements in laboratory animals. The nanoparticles synthesized at 80 degrees C, the ones giving the largest specific absorption rate values, have been functionalized with different organic ligands to study the influence of functionalization on specific absorption rate values. In all the synthesized nanoparticles, with and without organic surroundings, specific absorption rate measurements have been performed to study the influence of applied magnetic field intensity an frequency.
