L. monocytogenes (L. m) is one of the most common causes of foodborne diseases. To enable timely monitoring of L. m contamination, a highly efficient and sensitive electrochemical biosensor was developed for the precise determination of L.m. The biosensor was prepared by sequentially modifying glassy carbon electrode (GCE) with silicon methylene blue (Si@MB), gold nanoparticles (AuNPs) and aptamer (Apt). Differential pulse voltammetry (DPV) was used to quantify L.m. This biosensor could be finished in 1.5 h, which significantly reduced the detection time. The resulting electrochemical biosenso...
