Researchers at the University of Tokyo’s Life Bio Electromechanical Autonomous Nano Systems Center recently reported in the Proceedings of the National Academy of Sciences that they had developed injectable fluourescent microbeads that glow when exposed to blood glucose.  Coated with diboronic acid, the beads were implanted in mice ears, and glowed with intensity relative to the level of glucose they detected.  For humans, this holds the possibility of less invasive blood sugar monitoring.  MORE
