<unk>  <unk>  refers to efforts to use electromagnetic radiation (most often in infrared wavelengths) for the treatment of various medical conditions, including cancer. This approach is an extension of photodynamic therapy, in which a photosensitizer is excited with specific band light. This activation brings the sensitizer to an excited state where it then releases vibrational energy (heat), which is what kills the targeted cells. Unlike photodynamic therapy,<unk>  does not require oxygen to interact with the target cells or tissues. Current studies also show that<unk>  is able to use longer wavelength light, which is less energetic and therefore less harmful to other cells and tissues.
