Biomedical researchers at Draper Laboratories are working on a blood glucose monitoring nano ink tattoo that will allow diabetics to say goodbye to the daily routine of painful needles. This cool tattoo allows you to manage diabetes and look tough at the same time.
This new technology would require the apply of a one time small tattoo on the arm. The tattoo contains a glucose detecting ink that changes color based upon the blood glucose levels.
The nano ink particles are tiny, squishy spheres about 120 nanometers across. Inside the sphere are three parts: the glucose detecting molecule, a color-changing dye, and another molecule that mimics glucose. If the molecules mostly latch onto glucose, the ink appears yellow. If glucose levels are low, the molecule latches onto the glucose mimic, turning the ink purple. A healthy level of glucose has a “funny orangey,” color, according to Clark. The sampling process repeats itself every few milliseconds.
