A series of Figures showing the different steps of a treatment of MDA-MB-231 breast tumors xeno-grafted under the skin of a mouse using magnetic hyperthermia. The nanoparticle suspensions are first administered to the tumors, (a). The mouse is then positioned inside a coil that generates an alternating magnetic field of average field strength 20 mT and frequency 198 kHz to heat the nanoparticle contained in the tumors, (b). The treatment results in the disappearance of the tumor using the magnetosomes, (c), while it does not destroy the tumor using chemically synthesized nanoparticles, (d).
