Implantable LED device uses light to treat deep-seated cancers

Certain types of light have proven to be an effective, minimally invasive treatment for cancers located on or near the skin when combined with a light-activated drug. But deep-seated cancers have been beyond the reach of light’s therapeutic effects. To change this, engineers and scientists have devised a wireless LED device that can be implanted. This device, when combined with a light-sensitive dye, not only destroys cancer cells, but also mobilizes the immune system’s cancer-targeting response. …read more
