Comparison of polyacrylonitrile-and polypyrrole-based electrochemical sensors for detection of propamocarb in food samples. Journal of the Turkish Chemical Society, Section A: Chemistry. 9(3), s.801–808.10.18596/jotcsa.1087096.https://doi.prg/10.18596/jotcsa.1087096.https://hdl.handle.net/20.500.12415/3214Food safety is a crucial issue; all countries have struggled against pesticides for years. In this study, Polypyrrole (PPy)- and Polyacrylonitrile (PAN)-based non-enzymatic electrochemical sensors were investigated to detect the pesticide propamocarb (PM) in food samples. Under the experimental conditions, the proposed strategy exhibited a high selectivity of the disposable PPy-based and PANbased sensors for the determination of propamocarb pesticide in the concentration of 1 ?M with a rapid detection within 1 min at pH 7.4 and 25 °C. We demonstrated the detection of PM residues on cucumber and tomato samples with good electrochemical performances towards the real-time usability on real food samples. PAN-based non-enzymatic electrochemical sensor has good sensitivity, higher selectivity, and stability than PPy-based non-enzymatic electrochemical sensor. The prepared PAN-based nonenzymatic electrochemical sensor is a potential candidate to be used in devices which perform food safety in agricultural products.eninfo:eu-repo/semantics/openAccessFood safetyPesticideElectrochemical sensorPolypyrrolePolyacrylonitrileArticle808380111164369
