Tattoo to Test Blood

2274

Blood TestingResearchers at Draper Laboratory are developing “tattoo sensor” that could monitor blood composition. “Tattoo” is designed to report the results right through the skin. Heather Clark and her colleagues are creating a special ink consisting of polymer beads coated with biocompatible material.

Within each bead is an element that becomes fluorescent as a reaction to specific chemicals. Injected under the skin, much like tattoo dye, this safe sensor could tell about the presence (including quantity) of different substances in blood. “Tattoo sensors” will help diabetics and other people who need to monitor their blood.
