Team of physicists and engineers at Case Western Reserve University in Cleveland, OH, has created an optical biosensor for cancer detection using nanostructured metamaterials that are 1 million times more sensitive than previous versions, pointing the way toward an effective early detection system for cancer and other illnesses.
The device, which is small enough to fit in the palm of a hand, has been developed to provide oncologists with a way to detect a single molecule of an enzyme produced by circulating cancer cells.
