Hybrid Fabrication Makes Better Plasmonic Nanostructures for SERS Monolithic hierarchical plasmonic nanostructures improve results from surface-enhanced Raman spectroscopy. Plasmonic nanostructures of gold and silver have emerged as attractive nanomaterials because of their small size, corrosion resistance, biocompatibility and ability to bind to a wide range of thiolated molecular and biomolecular species through the metal-S bond. These nanostructures absorb and resonantly scatter visible and near-IR light upon excitation of the localized surface plasmon resonance, which can be tuned over a wide spectral range by changing intrinsic parameters such as material composition or particle size and shape.
