Plasmonic substrate is a key component in surface-enhanced Raman scattering (SERS) spectroscopy to boost the Raman signal of analytes. The quality of SERS substrate is assessed primarily on the basis of its sensitivity, reproducibility and robustness

International audience; Nanometric gaps in plasmonic structures can lead to huge optical near fields and, related, to strongly enhanced interaction of molecules and light. Nanocavities formed by sphere-on-film or cube-on-film systems were recently es

We describe a simple and effective strategy to couple gold nanorods (GNRs) into end to end dimers and freeze the assembly in water. The assembly is initiated using cysteine and driven by hydrogen bonding between two cysteine. We show that the aging o

Highly stable silica-coated gold nanorods dimers for solution-based SERS

Autor: Leïla Boubekeur-Lecaque, Stéphanie Lau-Truong, Nordin Félidj, Daniel R. Neuville, Georges Lévi, Johan Grand, Jean Aubard, Ludovic Mouton, Israa Haidar

The controlled assembly of anisotropic plasmonic nanoparticles (NPs) into highly SERS-active substrates remains particularly challenging for the production of long-term stable NP assemblies in suspension. In this work, we report a simple and efficien

International audience; The chemisorption of 1,3,4‐oxadiazole‐2‐thiol (ODT) on gold nanorods has been investigated by using surface‐enhanced Raman spectroscopy (SERS) and density functional theory (DFT). Although most of the SERS spectra have
