Abstract
A method for diagnosing certain types of cancers provides a nanoparticle agent to be uptaken by cancer cells for diagnosis and treatment of certain cancers. A compound containing nanoparticles is directed toward a tumor site, and then a predetermined time period passes to allow the nanoparticles to be uptaken by the cancer cells. Imaging is then performed on the nanoparticles by an appropriate imaging device to determine the concentration of nanoparticles uptaken by the cancer cells. Finally, image data provided by the imaging device is analyzed to determine the concentration of nanoparticles and thereby determine whether a tumor is present. The nanoparticle agent can further be employed as a treatment of certain cancers. After the uptake of nanoparticles into the cells, a predetermined field applied to the nanoparticles for a sufficient period of time activates the magnetic cores of the nanoparticles to include hyperthermia-mediated destruction of the cancer cells.
