The Glucose-Monitoring Tattoo, Draper Laboratory, Inc. Study

Published: Jan 26, 2009

MIT Technology Review -- It's a modern medical twist on an ancient art. Scientists at Draper Laboratory, in Cambridge, MA, are developing a nanosensor that could be injected into the skin, much like tattoo dye, to monitor an individual's blood-sugar level. As the glucose level increases, the "tattoo" would fluoresce under an infrared light, telling a diabetic whether or not she needs an insulin shot following a meal. The researchers have already tested a sodium-sensing version of the device in mice, and will soon begin animal tests of the glucose-specific sensor.
