Edible QR Codes Could Deliver Exactly What Your Body Needs to Heal

A team of researchers from the University of Copenhagen, in collaboration with colleagues from Åbo Akademi University in Finland, believe they’ve come up with a new solution to producing medicine with more accurate dosage: edible QR codes. Okay, maybe it’s not a radically different idea, since you still have to consume something, but there’s more to it than how it gets into the body. And it’s probably easier to swallow than a tiny, unfolding robot.
