New Biochip Measures Glucose Levels in Saliva

Through the wonders of nanotechnology, engineers from Brown University have designed a biochip that can check blood glucose levels as well as other chemical concentrations by manipulation of light waves from saliva. The obvious application would be for diabetics checking their levels painlessly, but the device can be tailored for numerous applications.

The researchers, who have published their proof-of-concept in Nano Letters, say the device should be able to simultaneously detect a wide range of chemicals or substances, including anthrax, using just one chip.
