Alchemically-glazed plasmonic nanocavities using atomic layer metals: controllably synergizing catalysis and plasmonics
Monolayer Pd deposition and characterization
To uniformly glaze an atomic layer of catalytically-active Pd onto NPoMs (Fig. 1a), a template stripping method is used to fabricate atomically-smooth Au films (Supplementary Fig. 1). Citrate based…

Plasmonic nanorod and dimer chiral molecule sensing from cysteine monolayer to bi-layers and multilayered shells
Chiral properties of the single and dimer AuNR assemblies
We first investigated the CD signal of AuNRs and pure Cys. Zero CD signal is observed for pure AuNRs in the absence of Cys molecules, consistent with the fact that AuNRs act as nonchiral…
