A Raman spectroscopy device was used to non-invasively monitor their blood glucose over a two day period. This uses a near-infrared light of 830nm wavelength, positioned over the person’s thumb.

Stimulated Raman scattering (SRS) imaging of glucose uptake activity by targeting the alkyne tag of a novel glucose analogue in live mouse brain hippocampal neurons and tumor tissues (in red).

Over the past several years, researchers have found that blood glucose levels can be gleaned using Raman spectroscopy aimed at the skin. Unfortunately, most such attempts have been hampered by ...

The study, entitled “Calibration and performance of a Raman-based device for non-invasive glucose monitoring in type 2 diabetes”, involved 50 people with type 2 diabetes over a two day period.
