Aptamer/magnetic-MIP dual-recognition sandwich biosensor for rapid and recyclable determination of kanamycin in food.
BACKGROUND The rapid and precise monitoring of antibiotic residues is a cornerstone of food safety and diagnostic science. Herein, we report a high-performance dual-recognition sandwich-type fluorescent biosensor engineered by integrating Fe3O4@UiO-66-based molecularly imprinted polymers (FUMIP) with a fluorescein-labe...
