Patent ID: 10773095

Abstract:
Devices and methods for identifying and destroying cancer cells are disclosed. Devices and methods may relate to techniques of imaging and/or irradiating cells bearing a plurality of surface-modified superparamagnetic iron oxide nanoparticles (SPIONs) therein. Imaging can be realized with a magnetic imaging device that generates an imaging magnetic field. A magnetic field associated with the SPION-bearing cancer cells and resulting from imaging, can be detected with a detection device. Irradiation can be realized with a magnetic field emission device that generates an irradiation magnetic field such that the SPIONs in the SPION-bearing cells are heated as a result of said magnetic field, thereby killing the SPION-bearing cells. The magnetic imaging device may be used as the magnetic field emission device. The magnetic fields produced for imaging and/or irradiating, as well as the associated magnetic field, can be focused using one or more magnetic metalens devices.
