Design of Novel Electrochemical Sensors for the Selective Detection of Glyphosate

This study concerns the development of two molecularly imprinted polymers (MIP) based electrochemical sensors for glyphosate detection. In both cases polypyrrole (PPy) was chosen as matrix and glyphosate molecules were the templates. The main difference between the two strategies is related to the investigated electrode: gold surface in the first case, and ZnO nanorods vertically grown on ITO diazonium modified substrates in the second case. The limits of detection (LOD) of these sensors were about 10−13 M and 10−10 M respectively.
