Shining a Light Literally on Diabetes

People with type 1 diabetes must keep a careful eye on their blood glucose levels: Too much sugar can damage organs, while too little deprives the body of necessary fuel. Most patients must prick their fingers several times a day to draw blood for testing.

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.
