Summary

Story summary

Massachusetts Institute of Technology (MIT) researchers are developing a noninvasive blood-glucose monitor using Raman spectroscopy that could replace finger pricks.
The light-based device aims to be watch-sized, offering a compact option described in Analytical Chemistry.
Currently, wearable monitors rely on under-skin sensors and frequent replacements, causing irritation.
The device evolved from a larger prototype to shoebox size, and researchers aim to further miniaturize it to work across all skin tones.
