N2 - Substrate design has attracted much interest in development of an effective surface enhanced Raman scattering (SERS) sensor. A flexible SERS substrate with excellent performance needs to be sensitive to details of the preparation process; this sensitivity represents a significant challenge for practical applications as opposed to laboratory research applications. Here, a 3D flexible plasmonic structure, AgNPs@MoS2/pyramidal polymer (polymethyl methacrylate), is fabricated using a simple and low-cost method. Using experiments and theoretical simulations, the SERS performance of the proposed substrate is assessed in terms of its high enhancement factor, ultrasensitivity, quantifiability, reproducibility, stability, and reusability. Finally, the ultralow in situ detection limits of the standard melamine solution and melamine in milk are found to be 10−10 and 10−6m, respectively, which meet the demand for real applications in the food security field.
