Searching PubMed for the terms "non-invasive blood glucose monitoring" AND "near-infrared spectroscopy" provides a handful of results.

Perhaps there are some articles that are interisting for you.
The Journal of Diabetes Science and Technology (J Diabetes Sci Technol; http://dst.sagepub.com/) specializes in publishing research on new technologies.
Also at the annual sessions of the International Conference on Advanced Technologies & Treatments for Diabetes (ATTD) there are many contributions on new technologies. The abstracts of the ATTD meetings are published in supplementum issues in the journal Diabetes Technology & Therapeutics which are freely available at the journals homepage.
Dear Prabodhi, some times ago you asked this question on non-invasive glucose measurement. But from your side, there were no further answers, questions or comments. Is this project still running? It would be interesting to know whether and how the project is running. Kind regards.
