Injectable nanotech device continuously monitors glucose

Kyungsuk Yum at the University of Texas is developing an internal, nanoscale device to continuously analyze blood sugar.   A near infrared optical biosensor nanotube is injected, and an optical scanner accesses data for constant monitoring .

Current continuous monitoring technology for diabetes requires a tube inserted through the abdomen.  This reads glucose levels in tissue, which is not as accurate as blood reading.  It must be calibrated several times per day, and changed every week.

The traditional glucometer system requires blood-drawing finger pricks throughout  the day.
