Quantune joins quest for the holy grail of non-invasive glucose monitoring

Berlin-based Quantune is trying to shrink laser spectrometers so that you can wear one on your wrist, and it just raised $9M to do it.

Laser spectrometers are normally bulky devices that can measure glucose and other molecules non-invasively in interstitial fluid, which nourishes all the cells and is present right below the skin, Kischkat explained. The company’s goal is to embed its technology in a wrist-worn device that can be used by anyone, not just diabetics, since continuous blood glucose monitoring has many applications in sports and weight management. While these devices offer significant benefits, they still require a small, needle-like sensor inserted under the skin to measure glucose levels.
