Using a mouse model of cancer, researchers led by Samuel Achilefu, Ph.D., at Washington University School of Medicine in St. Louis have devised a way to apply light-based therapy to deep tissues never before accessible. Instead of shining an outside light, they delivered light directly to tumor cells, along with a photosensitive source of free radicals that can be activated by the light to destroy cancer. And they accomplished this using materials already approved for use in cancer patients. The study appears March 9 in the journal Nature Nanotechnology.
