Glucose sensor tests saliva

After Polynesians, Arab peoples have the world’s highest incidence of diabetes, and for that reason it’s no surprise that engineers at King Abdullah University of Science and Technology have developed a glucose monitor that uses saliva for input.  “The plastic device . . .  combines an electron-transporting polymer with a redox enzyme for the autonomous detection of glucose and power generation from bodily fluids. The n-type semiconducting polymer is coupled with the glucose oxidase enzyme, which oxidatively extracts electrons from its reaction with glucose.”  MORE
