Anisotropic Metal Nanoparticles for Use as Surface‐Enhanced Raman Substrates

Abstract

Silver platelets and silver-coated gold nanorods 20–100 nm in size (with a 10–20 nm short axis; see figure) have been identified as excellent candidates for surface-enhanced Raman spectroscopy (SERS) substrates. Salt-induced particle aggregation is essential in obtaining high sensitivity.
