A new biosensor detects tiny concentrations of glucose in saliva, tears, and urine—and may ultimately eliminate or reduce the need for pinpricks for diabetes testing.

We are proving its functionality,” says Jonathan Claussen, a former Purdue University doctoral student and now a research scientist at the US Naval Research Laboratory.
