Quantitative molecular detection based on surface-enhanced Raman spectroscopy (SERS) is still a great challenge because of the highly nonuniform distribution of the SERS hot spots and the nondeterministic spatial and spectral overlap of the analyte with the hot spot. Here. we report a nanoparticle-on-mirror plasmonic sensor excited by surface plasmon polaritons for quantitative SERS d... https://allfixelectricales.shop/product-category/microwave-lamp-cover/
