Tears of Joy for Diabetics
Nanocomposites could change treatment

Diabetics may soon be able to wear contact lenses that continuously alert them to variations in their glucose levels by changing colours - replacing the need to routinely draw blood throughout the day. The non-invasive technology uses extremely small nanoparticles embedded into the hydrogel lenses.

Diabetics may soon be able to wear contact lenses that continuously alert them to variations in their glucose levels by changing colours - replacing the need to routinely draw blood throughout the day.

The non-invasive technology, developed by Chemical and Biochemical Engineering professor Jin Zhang at The University of Western Ontario, uses extremely small nanoparticles embedded into the hydrogel lenses. These engineered nanoparticles react with glucose molecules found in tears, causing a chemical reaction that changes their colour.

Zhang received $216,342 from the Canada Foundation for Innovation (CFI) today (Dec. 16) to further develop technologies using multifunctional nanocomposites.

These technologies have vast potential applications beyond biomedical devices, including for food packaging. For example, nanocomposite films can prevent food spoilage by preventing oxygen, carbon dioxide and moisture from reaching fresh meats and other foods, or by measuring pathogenic contamination; others can make packaging increasingly biodegradable.

Very cool, though you're bound to get a few people who are more afraid of putting in contact lenses than they are of drawing blood :lol:

Yup, I'm one of those. Wearing contacts freaks me out completely. I'm completely fine with blood, on the other hand.

+1. I have a fear of losing my vision/getting things in my eye.

I must be one of the few that doesn't have a problem with either contacts or drawing blood, but as I'm not diabetic that's not really relevant.

I can't help but wonder... I assume you'd have to look in the mirror to notice the change of colour, (I really should read news stories before commenting on them) and if so, how often would you have to gaze upon your own reflection?
