Molecularly Imprinted Polymer-Enhanced Electrochemical Sensor for Sensitive and Selective Captan Detection in Fruit Sample.

ABSTRACT: In this study, a molecularly imprinted polymer (MIP) was designed for the selective, rapid, and sensitive electrochemical detection of Captan, a pesticide. The sensor was fabricated by electropolymerizing o-phenylenediamine (o-PD) onto a glassy carbon electrode (GCE) in the presence of Captan as the template molecule, using cyclic voltammetry (CV). Differential pulse voltammetry (DPV) was used to facilitate template removal and reattachment, optimize experimental conditions, and evaluate sensor performance. A ferrocyanide/ferricyanide redox indicator monitored each stage of the experiment via DPV. The MIP@o-PD/GCE sensor demonstrated a linear response to Captan within the concentration range of 1 × 10^-14 to 9 × 10^-14 M under optimal conditions, ma
