Contact Lenses that can Detect your Blood Sugar
Posted on: Tuesday, November 14th, 2006 at 11:10 amIt seems the researchers at the University of Santa Cruz have developed an optical glucose sensor to detect your blood sugar. This is very interesting and could (depending on its accuracy) provide a nice alternative to traditional blood sugar level detection.
“Recently published studies showed that the sensor detects glucose under physiological conditions, giving a reversible fluorescent signal that changes intensity in response to changes in the concentration of glucose.”
“The optical glucose sensor consists of a fluorescent chemical complex immobilized in a ‘thin-film hydrogel.’ The hydrogel, a biocompatible polymer similar to that used to make soft contact lenses, is permeable to glucose.The sensing system has two components: a fluorescent dye and a ‘quencher’ that is responsive to glucose. In the absence of glucose, the quencher binds to the dye and prevents fluorescence, while the interaction of glucose with the quencher leads to dissociation of the complex and an increase in fluorescence.”
From what I understand this is not “new” so-to-speak though they’ve made progression in the research over the past few years. Thought I didn’t see a release date or list prices, I can only assume this might be a costly alternative. They have to also get it approved and through the FDA. In any case, if you’re used to contact lenses and can’t stand the sight of blood or poking your fingers, this might be a solution for you.

It’s really a good research!! I am thinking of purchasing contact lenses and I have seen a good quality of contact lenses at CouponAlbum site….
