A Stylish Approach to Non-Invasive Glucose Testing

Posted by timothy on from the sounds-fun-for-non-diabetics-too dept.

legolas writes "ABC News has a story on a new blood sugar monitoring tool being developed for diabetics by the University of Pittsburgh. Using special "photonic crystals" (materials that change colours in the presence of specific chemicals), Dr. Asher's group is developing contact lenses that change colour in response to the blood sugar level in the diabetic's tears. Instead of needles, the diabetic need only a mirror." Maybe the insulin can be stored there too.

    "The ideal is that it's on the bottom edge of the lens and the diabetic patient would look in a mirror and see a color and relate it to a color wheel to [determine the] concentration of glucose," says Ascher.

    Visually matching against a color wheel? This doesn't seem very accurate. Accuracy is key. The existing way seems much better.
