NANOCOMPOSITES COULD CHANGE DIABETES TREATMENT

The people who are suffering from diabetes may soon be able to wear contact lenses that continuously alert them to variations in their glucose levels by changing colors. This facility reduces 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 color.

Zhang received $216,342 from the Canada Foundation for Innovation (CFI)  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.
