Introduction to Chemiluminescence immunoassays
One of the most promising applications of magnetic nanoparticles in medicine is their use for killing cancer cells by hyperthermia. You can place the nanoparticles in the right place by functionalizing them with antibodies specific to the membranes of the cancer cells and/or applying a magnetic field gradient to focalize them in a predetermined region of the body. If you apply an alternate magnetic field, the nanoparticles will heat and, they will kill the cells they are attached to. With the appropriate intensity and frequency, the increase in temperature will just be a few degrees and the effect would be very localized and selective.
