Disposable paper-based sensors that can measure glucose concentrations in saliva have been developed by scientists, paving the way for a pain-free alternative to diabetics for monitoring their blood sugar levels daily, says a study published in the Nature journal.

        A team from the Sensors Lab of the King Abdullah University of Science and Technology (KAUST) in Saudi Arabia have used inkjet technology to produce sensors that are sensitive to small sugar concentrations in biofluids. Inexpensive and easy-to-use diagnostic tools for fast health screening are imperative in todays world.
