Summary

Story summary

Massachusetts Institute of Technology (MIT) researchers have developed a noninvasive glucose monitoring device that uses near-infrared light to read blood sugar without needles.
The device is the size of a shoebox and uses Raman spectroscopy.
In initial tests, it showed accuracy comparable to glucometers.
A cellphone-sized prototype is undergoing clinical trials.
Plans to develop a wrist-sized version could reduce needle pricks and transform daily diabetes management.
