Organophosphorus pesticides rank among the most extensively used pesticides in agriculture, leading to widespread contamination of water bodies, soil, and vegetation, thereby disrupting ecosystems and posing health risks. Consequently, rapid and precise detection of organophosphorus pesticide residues is crucial for effective pesticide management. Conventional analytical methods such as chromatography and spectroscopy rely on sophisticated equipment and specialized personnel, incurring high costs and time consumption. In response, this study presents an innovative approach involving the development of aptamer-based colloidal gold lateral flow test strips for the swift and accurate detection of residual organophosphorus pesticides in fruits and vegetables. These test strips offer advantages such as sensitivity, portability, and ease of operation, enabling on-site application in real sample detection and demonstrating excellent applicability. Furthermore, the logical operation process of these test strips facilitates science popularization and education. Diverse experimental processes and schemes tailored for different audiences serve to stimulate interest in chemistry and science while enhancing awareness of food safety.
