Now here is something for the NANO Supermarket: Massachusetts-based Draper Laboratories have developed a special injectable ink with nano–particles. This ink eventually could replace painful blood glucose tests which diabetics need to do on a regular basis.
Squishy nano spheres, embedded in the ink, consist of three different parts: a glucose detecting molecule, a color changing dye and a glucose mimicking molecule. Those three parts continuously move around in the sphere, approaching the surface the glucose detecting molecule either latches onto the mimicking glucose molecule or a glucose molecule making the color of the sphere change either to yellow or orange. The sampling process repeats itself every few milliseconds and is therefore much faster then most current blood testing systems.
Will the next step be to let our skin tell when we’re irritated or happy?
