NOVELTY - Detecting imidacloprid by electrochemical sensor comprises introducing graphene ethylene glycol (GE) on the surface of the glassy carbon electrode, gold nano-silver nanoparticles and cyclodextrin (CD) film modified electrode sensor, using cyclic voltammetry to reduce GE into graphene oxide, and preparing GO/AuNPs/ ?-CD film-modified electrode sensor and establishing a novel method for detecting imidcloprid through electrochemical sensor. USE - The method is useful for detecting imidacloprid by electrochemical sensor which is useful in agricultural planting application, the residue in agricultural product e.g. banana. ADVANTAGE - The method enables to detect imidacloprid by electrochemical sensor, which has high sensitivity, and high recovery rate, and improves the sensitivity of the sensor, and provides improved detection sensitivity of imidocloprid residue in farm product sample e.g. banana to effectively improve the yield of the product.
