Nanosensor Tattoos

Scientists are developing nanosensors, injected like tattoo ink, that can monitor chemical levels including glucose. The nanosensors chemically determine the level of the targeted substance and fluoresce (with infrared light) to indicate concentrations. Sodium sensors are now being tested in mice.
