Development of Dieldrin, Endosulfan, and Hexachlorobenzene-Imprinted Polymers for Dye-Displacement Array Sensing

Due to the toxicity associated with the exposure to organochlorine pesticides, new materials capable of selectively capturing and detecting these compounds are highly desirable. In this study, imprinted polymers were prepared using three organochlorine pesticides—dieldrin (DE), endosulfan (EN), or h...
