Surface‐Enhanced Raman Scattering of Small Molecules from Silver‐Coated Silicon Nanopores

Abstract

New ways of detecting low concentrations of analytes , which could be used as part of integrated on‐chip devices, are offered by surface‐enhanced Raman‐scattering substrates fabricated on the nanoscale. The ability of metal surfaces to amplify a Raman‐scattering signal (see Figure) is combined with an enlarged substrate surface area, allowing orders of magnitude enhancement for the detection of rhodamine 6G and adenine.
