New Breakthroughs in Lighting Up Cancer Cells to Find and Destroy Cancer
Grades: 6 - 12

Video Description: New research is successfully using light as a precision weapon against cancer by creating an army of light-triggered nanoparticles to lead the attack. The new strategy is using light as a weapon against cancer cells that have spread deep inside the body in animal studies at Washington University School of Medicine in St. Louis. Samuel Achilefu, PhD, the Michel M. Ter-Pogossian Professor of Radiology at the School of Medicine, has proven how this technique can target and attack cancer cells when light emitted from a common cancer imaging agent causes tumors to glow.
