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.
For those interested, here’s the link to the peer reviewed journal article:

This would be lovely. I rotate through my fingers, first pricking one side of each finger on each hand, then the other side, but they seldom heal faster than I need to test BG.
As things stand, I’ll have to keep doing this a few times a day for the rest of my life. Replacing the lancet with an IR light would significantly improve my quality of life.
