New Nanoparticle Tattoos Can Monitor Glucose Levels in Diabetics

For some people, staying healthy could require getting some ink. Researchers at MIT [2]recently created a new type of tattoo [3] designed for folks living with diabetes. Once injected, the nanoparticle ink [4] can consistently measure glucose levels in the bloodstream, alerting patients if their blood sugar levels fall outside the normal range.

We’ve seen similar tattoo technology from a different lab covered before on Ecouterre [4], and now we’re excited to see that MIT is getting in on the action – tattoos such as these [4] offer a huge advance in glucose-level monitoring. Typically, diabetics need to prick their fingers several times a day in order to monitor blood sugar levels. Not only is this method a nuisance, it’s not entirely effective: By not consistently tracking glucose, diabetics can miss the moment when blood sugar levels start to change, like after eating. While some constant monitors exist, they’re not approved for long-term use.

To create the blood sugar-reading ink [3], scientists used nanotubes wrapped in a glucose-sensitive polymer. After the ink is injected beneath the surface of the skin, the nano-ink seeks out glucose [6] and fluoresces when it detects it. A separate device kind of like a wristwatch provides near-infrared to read the fluorescing (kind of like a secret decoder ring), and allows users to track rising and falling glucose levels.

While all this is pretty fascinating, it gets better: Wearers aren’t stuck with the same tattoo for life. The nano-ink [3] starts to disappear after about six months, when patients will need to be re-injected with the ink.
