Résumé

A novel sandwich assay for the detection of L. monocytogenes was designed based on antibiotic magnetic separation and enzymatic colorimetry. PEG-mediated cefepime functionalized magnetic nanoparticles (Cefe-PEG-MNPs) was reported for the first time to anchor L. monocytogenes cells with excellent bacterial capture capacity. The capture efficiency of L. monocytogenes in lettuce sample with high concentration (3.1 × 10
