Sensor identifies glyphosate in droplets of liquid in a laboratory

A newly developed sensor can detect and accurately measure the amount of the widely used and controversial herbicide, glyphosate, in droplets of liquid in a laboratory test.

Washington State University and DL ADV-Tech engineers developed the sensor, which uses nano-sized tubes.

The sensor developed by the research team uses electrically conducting polymer nanotubes that are imprinted with molecule-sized cavities that can bind glyphosate molecules – essentially mimicking the biological antibodies.

These nanotubes are then coated on a 3D-printed sensor device that uses an electric current to quantify the glyphosate concentration.
