Unless you are a True Blood diehard, the concept of bleeding yourself intentionally shouldn’t really seem all that appealing. So imagine how most diabetics feel when they’re forced to prick their thumbs thrice an afternoon within the name of health. Well, soon they won’t ought to owing to a nanosensor tattoo and… an iPhone? Developed by Prof. Heather Clark and her Northeastern University team, this injection of subdermal nanoparticles combines “fluorescent dye, specialized sensor molecules…and a charge-neutralizing molecule” that attach to glucose, releasing ions and altering the tat’s glow within the process. The researchers had originally designed a “large boxlike” tattoo-reading device, but an apparent Apple fanboy at the team modded an iPhone case with LEDs and a filter lens to make the complete affair a little more stylish. Next up for the team is, you guessed it, an app for that — although this one’ll specialise in sodium.
