A new device developed by scientists in the United States measures blood sugar levels in saliva, so that diabetics do not have to draw blood when checking their levels.
The study, published in the journal Nano Letters, involved thousands of plasmonic interferometers being etched onto a biochip that was then able to measure the concentration of glucose molecules in water. Small alterations in the intensity of the light passing through the slit of each plasmonic interferometer provides data on the concentration of glucose molecules in solution.
