‘Nano-tattoos’ could not only eliminate the need for finger pricks but also offer more accurate readings.

Many diabetics endure daily finger pricks to test their blood sugar levels. But advances in nanotechnology could soon mean that diabetics need endure the needle only once: to get a glucose-tracking tattoo.


Postdoctoral researcher Paul Barone and professor Michael Strano of MIT’s Department of Engineering are working to develop nanoparticle tattoos that will allow diabetics to constantly monitor their glucose levels. Studies have found that it’s more effective for diabetics to constantly monitor their blood sugar than to test it a few times each day. But the technology currently available for constant monitoring — such as wearable devices — offers less accurate readings than finger pricks and still requires drawing blood.
