Today millions of people suffer from type I and type II diabetes, and the associated mortality rate is on the rise. Diagnostic monitoring of glucose is critical to help control blood glucose levels in patients. Currently, various self-monitoring enzymatic strips, and electrochemical sensors are commercially available. However, the high expense, conditional accuracy, and invasiveness are hurdles, which still need to be overcome. Optical detection for glucose monitoring has made significant advancement over the years. Jasmine Pramila Devadhasan and Sanghyo Kim from Gachon University, South Korea have developed a glucose oxidase based sensor using the power of Complementary Metal Oxide Semiconductor (CMOS) imaging to detect glucose levels by photon count variation. Find out more about this discovery below.
