Synthesis of hybrid gold-protein nanobioconjugates with strongly enhanced circular dichroism
Yoann Prado, Victoire Ho, Maud Virolle +7
Controlling chiral light-matter interactions with nanophotonics is a powerful strategy for amplifying molecular circular dichroism (CD) beyond its natural limits. Here, we present…

Probing Peptide Adsorption Kinetics and Regioselectivity via Multipolar Plasmonic Modes of Gold Resonators
Mathieu Nicolas, Shuhui Yang, Christophe Méthivier +2
Efficient peptide adsorption on metasurfaces is essential for advanced biosensing applications. In this study, we demonstrate how ellipsometric measurements coupled with numerical…

The Prevailing Role of Hotspots in Plasmon-Enhanced Sum-Frequency Generation Spectroscopy
Laetitia Dalstein, Christophe Humbert, Maroua Ben Haddada +3
The plasmonic amplification of non-linear vibrational sum frequency spectroscopy (SFG) at the surfaces of gold nanoparticles is systematically investigated by tuning the incident v…
