> New Delhi, Aug. 9: An ... engineer at the Massachusetts
> Institute of Technology has helped devise a technique to
> monitor blood glucose using a beam of light that might
> eliminate annoying needle pricks.
> Ishan Barman is part of a research team trying to develop
> a non-invasive test for blood glucose, harnessing a light
> scattering phenomenon first described by Indian Nobel
> laureate C.V. Raman in 1928.
> The team has shown that it is possible to monitor blood
> glucose by shining a low-powered laser beam on the
> forearm and analysing the frequencies of photons that
> scatter, or bounce off. The photons that interact with
> any glucose molecules in the bloodstream return with
> glucose-specific frequency changes that may be used
> to quantify the glucose levels in the blood.
> "We're now at the proof-of-concept stage - the instrument
> we use is quite large," said Barman, who's pursuing a PhD
> at MIT. "But we're trying to develop a laptop-sized device
> that we hope to have ready within a year," he told The
> Telegraph.
> Researchers at MIT's Spectroscopy Laboratory have been
> pursuing a non-invasive test for blood glucose through
> Raman spectroscopy - a concept envisioned by the late
> MIT professor of physics Michael Feld - for nearly 15
> years.
> A major obstacle has been that a typical low-powered laser
> penetrates about half-a-millimetre below the skin where it
> can only measure the amount of glucose in the fluid that
> bathes the skin cells - the interstitial fluid.
> The interstitial fluid glucose levels are always slightly differ-
> ent from actual blood glucose levels. Although interstitial
> glucose levels may be used to compute blood glucose
> levels through a process of calibration, this requires fre-
> quent needle pricks.
> Barman ... helped develop a mathematical technique that
> allows the blood glucose readings to be predicted using
> interstitial glucose levels.

> The research is described in the current issue of the journal
> Analytical Chemistry.

> The next phase of the research ... will aim at developing a
> practical instrument that could be tested on a large number
> of human volunteers. It requires a low-powered laser of the
> type used in laser pointers - and a detector for the analysis
> of the light scattered by the tissues. "Our goal is to design
