New 3D-printed sensor can detect glyphosate in beverages

A newly developed, low-cost sensor can detect and accurately measure the amount of the widely used and controversial herbicide, glyphosate, in droplets of liquid in a laboratory test. Engineers developed the low-cost sensor, which uses nano-sized tubes, and tested it on orange juice and rice beverage samples they spiked with the herbicide for the study. The glyphosate sensor uses technology that is similar to that used in glucose tests that can quickly measure blood sugar levels from a pinprick of blood.
