Diabetics as we all know are on the constant watch to check their blood sugar levels. A new technology lets diabetics monitor their blood sugar levels with contact lenses that change as their blood sugar rises and falls.
Nanoparticles, proven winners are embedded in the hydrogel lenses and react with glucose molecules in tears. The chemical reaction causes the lenses to change color, alerting the diabetic to changes in blood sugar leveles.
U. of Western Ontario Professor Jin Zhang received $216,000 from the Canada Foundation for Innovation as a result of the breakthrough process to develop other applications for multifunctional nanocomposites, which can be used in everything from biomedicine to food preservation to packaging.
