Diabetic Smart Contact Lenses Developed by South Korean Research Team
POHANG, South Korea, Jan. 15, 2020 — A research team from Pohang University of Science and Technology in South Korea (POSTECH) developed technology that allows diagnosis of diabetes and treatment of diabetic retinopathy by wearing smart light-emitting diode (LED) contact lenses.
Researchers Engineer Light-Activated Cells for Treating Diabetes
MEDFORD, Mass., Nov. 5, 2019 — Tufts University researchers have shown that glucose levels can be controlled in a mouse model of diabetes through optogenetics. When exposed to light, engineered pancreatic beta cells transplanted into diabetic mice produced more than two to three...
Fiber Optic Biosensor-Integrated Microfluidic Chip Detects Glucose Levels
HONG KONG, May 3, 2016 — The lab-on-a-chip approach is being applied to the development of glucose meters for the early diagnosis and prevention of diabetes. An optofluidic device has enabled detection of glucose in solution, requiring only a tiny droplet of sweat. A team...
Far-Infrared Technique Noninvasively Measures Blood Glucose
TOHOKU, Japan, Feb. 10, 2016 — A light-based method for measuring blood glucose may give diabetes patients the daily monitoring they need without the pain and infection risk of conventional metering. Researchers from Tohoku University's Graduate School of Biomedical Engineering,...
Optical Glucose Sensor on Commercial Path
LEEDS, England, July 17, 2015 — A University of Leeds spin-out company is seeking to commercialize an optical glucose sensor that could make finger-prick blood tests unnecessary for people with diabetes. Glucosense Diagnostics Ltd. intends to make tabletop and wearable versions of...
Quantum Cascade Laser Tests Blood Sugar
PRINCETON, N.J., Aug. 25, 2014 — A new laser system could eliminate the need for conventional finger-prick tests for diabetics. A team from Princeton University has developed the new technique, which measures blood sugar by directing an IR quantum cascade laser at a person’s...
