Glucose `Tattoo` Could Track Blood Sugar Levels
By Mike Boyle

Thanks to researchers at the Massachusetts Institute of Technology (MIT) who are developing the new technology, people with diabetes may be able to monitor their blood sugar levels using a glucose "tattoo" in the not too distant future.

According to an article published by U.S. News & World Report, this new type of continuous glucose monitor relies on fluorescent nanoparticle ink injected under the skin to detect blood sugar levels with a watch-sized or smaller monitor worn over the skin.

The glucose "tattoo" ink would be made from carbon nanotubes that can reflect infrared light back through the skin to the monitor, and this new device has the potential to free people with diabetes from having to do numerous finger pricks each day or to change a continuous glucose monitor device every three to seven days to keep track of their blood sugar levels.

Commenting on the technology he and his team are working on, senior researcher Michael Strano, the Charles and Hilda Roddey associate professor of chemical engineering at MIT explained to U.S. News & World Report, "Carbon nanotubes will fluoresce in infrared light, and we can decorate the tubes so they fluoresce in response to glucose."
