A tiny (0.5 x 2 mm) biosensor no larger than a decent-sized upper eyelash is being tested to continuously monitor blood glucose levels without needle sticks. NovioSense analyzes tears or sweat for concentrations of hydrogen peroxide (H2O2) and other chemicals resulting from the electrochemical reaction with glucose oxidase, which then is used to calculate glucose levels. The device converts this information to digital data and sends to a mobile for upload to a website or to a glucose pump for regulating levels. Developed by Dutch medical technology firm NovioTech BV using a nanosensor developed by the Fraunhofer Institute for Microelectronic Circuits and Systems IMS in Duisburg, Germany. It does not yet have CE or FDA approval. GizMag Fraunhofer Institute article.
