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.

Abstract: Variations of the techniques, systems, devices, and methods discussed herein pertain to a pixel-level mask for a photo-detector. Such a mask may have a layer of reconfigurable phase-change material (PCM) configured to vary between a first refractive index and a second refractive index. Such a PCM layer may be divided into individual pixel areas such that each individual pixel area may be set to have the first refractive index or the second refractive index. The PCM layer may be disposed on a photo-detector such that incident radiation detected by the photo-detector must pass through the PCM layer in order to be detected. The mask may also include or otherwise be operably connected to a PCM controller that can control the refractive index of an individual pixel area or a group of pixel areas aggregated into a superpixel.
