Abstract:Here, a molecular imprinting technique was employed to create an SPR-based nanosensor for the selective and sensitive detection of organophosphate-based coumaphos, a toxic insecticide/veterinary drug often used. To achieve this, UV polymerization was used to create polymeric nanofilms using N-methacryloyl-l-cysteine methyl ester, ethylene glycol dimethacrylate, and 2-hydroxyethyl methacrylate, which are functional monomers, cross-linkers, and hydrophilicity enabling agents, respectively. Several methods, inclu… Show more
“…Organophosphate-based coumaphos is a very commonly used toxic insecticide, and an SPR-based nanosensor was prepared by Oymen et al . 77 that demonstrated high selectivity over competing molecules of the same class. And it has good linearity in the concentration range of 0.1–250 ppb, and the detection limit reaches 0.001 ppb.…”
Recently, surface plasmon resonance (SPR) biosensors have been widely used in environmental monitoring, food contamination detection and medical conditions due to their superior sensitivity, label-free detection and rapid analysis speed....

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
