Draper Laboratories of Massachusetts has developed a color-changing nanoparticle tattoo ink that can help diabetes patients monitor their glucose levels.
Heather Clark, a scientist at Draper, says that the nanoparticle tattoo wouldn't have to be terribly large to be effective for diabetes patients: "It doesn't have to be a large, over-the-shoulder kind of tattoo. It would only have to be a few millimeters in size and wouldn't have to go as deep as a normal tattoo."
