MagForce Nanotechnologies AG, a portfolio company of Germany's Nanostart AG, is focused on using nanotechnology to fight cancer. Its proprietary system of therapy is based on injecting aminosilane-coated iron oxide nanoparticles into a tumor which has already been localized. These nanoparticles are then subjected to a high-frequency alternating magnetic field, causing them to vibrate and produce heat which then damages or destroys the tumor cells. Depending on the temperature attained within the tumor, the method may be used either as hyperthermia therapy in support of conventional forms of treatment (such as radiation and chemotherapy) or byitself as thermoablation for the direct destruction of tumor cells. This approach, now in clinical trials but not yet commercially available, may be used for many different types of solid tumors, as fundamentally all tumor cells may be damaged or destroyed at a certain temperature.
