Can nano-tattoos be the next breakthrough for diabetes?

New nanoparticle tattooing could be used to monitor diabetics' blood sugar levels, replacing traditional daily finger pricks.

MIT's Department of Engineering is reportedly looking into the development of nanoparticle tattoos for diabetics that will serve double duty as monitors of blood-sugar levels, a daily concern for sufferers of diabetes. According to io9, researchers are reportedly close to animal testing phases, but still far from being able to test the effect of such monitoring tattoos on human beings. One primary benefit of such technology would be freedom for diabetics from daily blood level checks, usually involving fingertip pricks with devices that check for glucose content. With a nanoparticle tattoo, diabetics would be able to simply use a sensor to check.
