Take this as a start:

In vivo non-invasive monitoring of glucose concentration in human epidermis by mid-infrared pulsed photoacoustic spectroscopy M.Pleitez, T.Lieblein, A.Bauer, O.Hertzberg, H.v.Lilienfeld-Toal, W.Mäntele Analytical chemistry 85 (2013), 1013-1020

I would be more than happy to send you two publications an an executive summary for potential investors. Email me at: hn.40.yooy@spamgourmet.com

This is a very different method (FT-IR spectroscopy) than the device the original article uses (measuring electrical impedance). It is less surprising to me that FT-IR would be able to give accurate results - I would think the challenge would to be to keep costs down and be robust enough to handle the abuses of a wearable device or even a home-use device. Best of luck :)

I doubt that you have read the paper.

I would love to read them too. Who knows, maybe I can find the right person in the company I work for to invest.
