Comparison of Polyacrylonitrile-and Polypyrrole-based Electrochemical Sensors for Detection of Propamocarb in Food Samples

Food 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 experimental conditions, proposed strategy exhibited high selectivity of disposable PPy-based PAN-based determination concentration 1 μM with rapid detection within min at pH 7.4 25 °C. We demonstrated PM residues on cucumber tomato samples good performances towards real-time usability real sensor has sensitivity, higher selectivity, stability than sensor. The prepared potential candidate be used devices which perform agricultural products.
