Nichtinvasive Bildgebung könnte Fingerstiche bei Diabetikern ersetzen. MIT-Ingenieure zeigen, dass sie den Blutzucker genau messen können, indem sie Nahinfrarotlicht auf die Haut strahlen lassen.

**Noninvasive imaging could replace finger pricks for people with diabetes**

**MIT engineers show they can accurately measure blood glucose by shining near-infrared light on the skin.**

A noninvasive method for measuring blood glucose levels, developed at MIT, could save diabetes patients from having to prick their fingers several times a day.

The MIT team used Raman spectroscopy — a technique that reveals the chemical composition of tissues by shining near-infrared or visible light on them — to develop a shoebox-sized device that can measure blood glucose levels without any needles.

In tests in a healthy volunteer, the researchers found that the measurements from their device were similar to those obtained by commercial continuous glucose monitoring sensors that require a wire to be implanted under the skin.
