If you're a diabetic, you know how painful it is to prick your fingers every day in order to measure your blood sugar level. But there's some research being done that could put an end to that, and it comes in the form of a tattoo.
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.
Once inserted into the skin, glucose levels are detected, and the diabetic tattoo turns yellow or orange. You can only see the tattoo by positioning a device over it that reveals its color. "The darker the color, the more lower the sugar," said Puckett. "The lighter the color the more higher the sugar."
