Skin Implant Monitors Glucose Levels And Glows When They Change
Trial results for a long-term glucose monitoring device show it to be accurate and stable.
Researchers from the Institute of Industrial Science at the University of Tokyo and the Life Bio Electromechanical Autonomous Nano Systems Center in Japan have trialled a fluorescence-based sensor that has potential for long-term continuous glucose monitoring (CGM).
Published in the Proceedings of the National Academy of Sciences (PNAS), the trial aimed to overcome the limitations of current sensors, which lose accuracy and stability over an extended period. The researchers used glucose-responsive fluorescent hydrogel fibers, injected under the skin, which transdermally glowed and were found to continuously respond to blood glucose concentration changes for up to 140 days in mice.
