PLASMONIC CUVETTE MAY LEAD TO BLOOD-FREE TESTING FOR DIABETICS

Brown University Developing a Sensor That Detects Glucose in Saliva

Blood free glucose testing is the Holy Grail for researchers studying diabetes and other conditions. And a possible solution may be close at hand. Researchers at Brown University are developing a new type of sensor, they’ve called a “plasmonic cuvette” that may well be the first saliva-powered glucose meter.

This could mean the regular blood test diabetics must take would be a thing of the past. The sensor works using plasmonic interferometry (light based method of detecting chemical compounds) and a dual-enzyme assay that acts as a glucose marker. This is an exciting development and could soon lead, to what would surely be an indispensable product.
