New biochip measures glucose levels in saliva

Since blood has 100 times the sugar concentration as spit, pricking a finger to measure blood sugar has been the default way to figure out how much sugar is in a person’s system.  But now that might be about to change: a biochip that’s been developed at Brown University can use super-sensitive light interferometry to determine the level of glucose in saliva, even at an extremely low concentration.  What’s more, the same chip can be made to detect other chemicals, such as markers for disease and toxins.  Lots of potential, but still in early developmental stages; maybe ten years down the road?
