TLDR
In this paper, the authors review the contribution of electroanalytical methods for the determination of glyphosate in different food and environmental matrices, such as soil, water, and biological fluids, and show that electrochemical sensors are powerful detection system that can be improved by their design and by their portability to fulfil the needs of the GLY determination in laboratory benches, or even in situ analysis.About:
