Researchers Submit Patent Application, "Method For Rapidly Detecting Pesticide Based On Thin-Layer Chromatography And Enzyme Inhibition Principle", for Approval (USPTO 20240110900).

A patent application has been submitted for a method of rapidly detecting pesticides in agricultural products using thin-layer chromatography (TLC) and enzyme inhibition principles. The current mainstream method for detecting pesticides is the enzyme inhibition method, but it has limitations in terms of extraction efficiency and accuracy. The new method combines TLC with enzyme inhibition to overcome these limitations and improve the efficiency and accuracy of pesticide residue detection. The method involves cutting a TLC plate into a rectangle, using one end to contact a sample extract for pesticide residue separation, and covering the other end with filter paper or glass fiber for pesticide enrichment. The method shows promise in reducing interference from pigments and other substances in agricultural product samples. [Extracted from the article]
