Glucose Tattoos

Researchers at MIT are developing a "glucose tattoo" - a continuous blood sugar monitor that makes use of fluorescent carbon nanotubes (in the form of nanoparticle ink) placed under the skin to reflect infrared light back through the skin and to the monitor. They say the monitor itself will be watch-sized or smaller and could eliminate the need for daily finger pricking that many diabetics have to do. Check out the article here.
