Nano-ink Tattoos Could Continuously Monitor Glucose in Diabetics
People get tattoos for all kinds of reason, such as conveying their appreciation for Japanese calligraphy or to let others at the gym know their biceps are rugged like barbed wire. But a team of MIT researchers have found a higher calling for tattoo tech: using a nanoparticle ink to monitor glucose levels in the bloodstream. One of the main problems diabetics - and their doctors - have is continuously monitoring glucose levels. Usually, that involves several tiny pricks of the finger throughout the day to test their blood-sugar levels. This gives the patient a snapshot of where their blood sugar is right then and there, but it's often during brief periods when the blood sugar wanders outside of the normal range - right after a meal, for example - that diabetes can do its worst damage.
