True Circular Dichroism in Optically Active Achiral Metasurfaces and Its Relation to Chiral Near-Fields

Mathieu Nicolas, Per Magnus Walmsness, Jayeeta Amboli, Lu Zhang, Guillaume Demesy, Nicolas Bonod, Souhir Boujday, Morten Kildemo, Bruno Gallas

Optically active achiral metasurfaces offer a promising way to detect chiral molecules based on chiroptic methods. The combination of plasmonic enhanced circular dichroism and reversible optical activity would boost the sensitivity and provide enantiomerselective surfaces while using a single…

Functionalisation of gold surfaces with thiolate SAMs: Topography/bioactivity relationship – A combined FT-RAIRS, AFM and QCM investigation

E. Briand, C. Gu, S. Boujday, M. Salmain, Jean-Marie Herry, C.M. Pradier

Immobilisation of rabbit immunoglobulin G (rIgG) was performed by affinity binding to protein A (PrA) covalently bound to threedifferent thiolate self-assembled monolayers (SAMs), (i) a mixed SAM of mercaptoundecanoic acid (MUA) and mercaptohexanol(C6OH) at a molar ratio of 1–3, (ii) a pure SAM of…

Thermal Behavior of d -Ribose Adsorbed on Silica: Effect of Inorganic Salt Coadsorption and Significance for Prebiotic Chemistry

Mariame Akouche, Maguy Jaber, Emilie-Laure Zins, Marie-Christine Maurel, Jean-Francois Lambert, Thomas Georgelin

Understanding ribose reactivity is a crucial step in the “RNA world” scenario because this molecule is a component of all extant nucleotides that make up RNA. In solution, ribose is unstable and susceptible to thermal destruction. We examined how ribose behaves upon thermal activation when adsorbed…

Magnetic Traits in CoO‐Core@CoFe 2 O 4 ‐shell Like Nanoparticles

Nancy Flores-Martinez, Margot Roemer, Sarra Gam-Derouich, Patricia Beaunier, David Habrovsky, Souad Ammar

Antiferromagnetic (AF) CoO pseudo-single crystals 125±20 nm in diameter were prepared by forced hydrolysis in polyol and used as seeds to grow a poly- and nano-crystalline (5 nm in diameter) ferrimagnetic (F) CoFe2O4 shell. Transmission electron microscopy (TEM) showed a certain epitaxy between the…

The Prevailing Role of Hotspots in Plasmon-Enhanced Sum-Frequency Generation Spectroscopy

Laetitia Dalstein, Christophe Humbert, Maroua Ben Haddada, Souhir Boujday, Grégory Barbillon, Bertrand Busson

The plasmonic amplification of nonlinear vibrational sum frequency spectroscopy (SFG) at the surfaces of gold nanoparticles is systematically investigated by tuning the incident visible wavelength. The SFG spectra of dodecanethiol-coated gold nanoparticles chemically deposited on silicon are…
