Raman Device Measures Glucose Through Skin
A study in Analytical Chemistry reports researchers developed a shoebox-sized, band-pass Raman spectroscopy device that measures blood glucose noninvasively through skin in about 36 seconds. In a four-hour pilot with a healthy 27-year-old male, measurements every five minutes closely tracked two commercial invasive continuous glucose monitors and finger-prick readings. The prototype shows comparable accuracy in this single-subject trial and supports further larger validation studies.
Key Points
- 1Demonstrates band-pass Raman spectroscopy measuring glucose noninvasively from skin in under one minute.
- 2Provides comparable accuracy to commercial invasive continuous glucose monitors in a four-hour pilot trial.
- 3Enables potential portable, interpretable CGM without complex AI or full-spectrum acquisition, easing point-of-care use.
Scoring Rationale
Published peer-reviewed prototype shows strong clinical potential but limited by single-participant pilot and early-stage validation.
