Electrochemical Sensor System for Glyphosate Detection

Environmental effects of pesticides, especially on drinking water, are of key interest. Of the many herbicides, glyphosate is of particular interest, being at the top of the most used herbicides worldwide. A fast, robust, continuous and decentralized detection is highly relevant, and lab-on-chip devices with microsensors address these demands. In this study, the electrochemistry of glyphosate and its major degradation product AMPA were thoroughly investigated with gold working electrodes. A chronoamperometric method for glyphosate measurements was developed and successfully used in a microfluidic, lab-on-chip microsensor system.
