Overview
- In a peer‑reviewed Analytical Chemistry study, a shoebox‑sized prototype produced readings comparable to two invasive continuous glucose monitors during a four‑hour healthy‑volunteer test with two 75‑gram glucose drinks.
- Each scan took a little over 30 seconds, with measurements collected about every five minutes during the trial.
- The research team has built a cellphone‑sized wearable that is now undergoing small clinical testing at MIT’s Center for Clinical Translation Research in healthy and prediabetic volunteers.
- A larger hospital‑based study including people with diabetes is planned for next year, alongside work to validate performance across diverse skin tones and to shrink the hardware toward a watch‑sized form.
- Limiting detection to three Raman bands and using angled near‑infrared illumination reduced components and cost, enabling substantial miniaturization from earlier printer‑scale systems.
