Researchers at Texas A&M have designed a tattoo that responds to blood-sugar levels, replacing pinprick tests for people with diabetes.
Once perfected, the tattoo will allow glucose levels to be monitored round the clock, and could allow an alarm system that would warn the diabetic if their glucose levels were to fall dangerously…
It is made of polyethylene glycol beads that are coated with fluorescent molecules.
Because glucose displaces the fluorescent molecules, the level of fluorescence is high when bodily glucose levels are low.
