Abstract: A layer structure having a solid substrate having a surface, the surface carrying a layer including a molecularly imprinted polymer, wherein the molecularly imprinted polymer is adapted to bind a glyphosate analyte, wherein the glyphosate analyte is selected from glyphosate, a glyphosate degradation product, a metabolite of glyphosate or a metabolite of the degradation product of glyphosate, wherein a fluorescence characteristic of the molecularly imprinted polymer changes upon binding of the glyphosate analyte. Further, a method for detecting a glyphosate analyte in a sample includes: providing the layer structure having the molecularly imprinted polymer; providing a fluidic contact of the layer structure with the sample or an organic extract of the sample; measuring a fluorescence property of the layer structure; and estimating a concentration of glyphosate or of the glyphosate related analyte at least semi-quantitatively.
