FTNW: Needle-free diabetes testing

I have seen various reports on light based glucose testing and one rather extensive bit on why it will be very difficult if even possible. That said it is still in the news and here is the latest from


A new device based on Raman spectroscopy has been developed by scientists at MIT to help patients with diabetes monitor their blood glucose levels without needing to prick their fingers to take a blood sample...

..."The new device based on Raman spectroscopy is currently under development and we hope to have a functional prototype in the next two years," Barman told SpectroscopyNOW. "However, at this time, we have a portable instrument, which is relatively large, the size of a shopping cart, and can only be used for clinical studies. In fact, our feasibility studies which will start this Fall will be making use of this portable instrument that can be wheeled into a clinic but cannot be used for personal use."

"We will be starting [clinical] studies in September 2010," Barman told us. "We expect the initial series of studies to complete by the middle of next year. In the first trials, we will be testing our instrumentation and methodologies on healthy human volunteers. In the next set of investigations, we will be incorporating our primary target population of Type I and II diabetics. For our purposes, there is no difference between any diabetic patient (Type I, II or gestational) - however, if successfully implemented our technology would be most beneficial to Type I patients who need to perform 6-12 measurements per day."
