Photonic blood glucose measurement with infrared quantum cascade lasers

This is the authors' abstract. We don't add key points for this paper.

Diabetes patients rely on frequent measurement of blood glucose that is presently performed by painful pricking and analysis of a drop of blood. Diamontech has developed a noninvasive technique that targets a prominent mid‐infrared signature of glucose. This technique uses quantum cascade lasers and photothermal detection. Clinical validation has proven an accuracy similar to current invasive techniques.
