For most sufferers of type 1 diabetes pricking their fingers several times a day to draw blood for testing is an annoying (and often painful), but necessary part of life. It is essential to keep an eye on blood glucose levels because too much sugar can damage organs, while too little deprives the body of necessary fuel. To minimize that pain and inconvenience, researchers at MIT’s Spectroscopy Laboratory are working on a noninvasive way to measure blood glucose levels using light.
