Brown University Study: Biochip measures glucose in saliva, not blood

Scott Benner

Researchers at Brown University have developed technology that can measure glucose in human saliva.

 

Engineers at Brown University have designed a biological device that can measure glucose concentrations in human saliva. The technique could eliminate the need for diabetics to draw blood to check their glucose levels. The biochip uses plasmonic interferometers and could be used to measure a range of biological and environmental substances.

Tripping the light fantastic Each plasmonic interferometer – thousands of them per square millimeter – consists of a slit flanked by two grooves etched in a silver metal film. The schematic shows glucose molecules “dancing” on the sensor surface illuminated by light with different colors. Changes in light intensity transmitted through the slit of each plasmonic interferometer yield information about the concentration of glucose molecules in solution.Credit: Domenico Pacifici
