Electroactive molecular layers produced by reduction of an aryldiazonium salt scrutinized by Tip Enhanced Raman Spectroscopy

Thomas Touzalin, Jessem Landoulsi, Laure Fillaud, Ivan T Lucas, Emmanuel Maisonhaute

Surface modification methodologies are continuously refined, which in parallel necessitates accurate analytical methods to probe their chemical composition at the nanoscale. We describe here our electrochemical and Tip Enhanced Raman Spectroscopy results on surfaces modified through reduction of an…

Synthèse et fonctionnalisation de nanobâtonnets d’or enrobés de silice AuNR@SiO2 pour des applications aux biointerfaces, Synthesis and functionalization of silica coated gold nanorod AuNR@SiO2 for biointerfaces applications

Vincent Pellas

Les nanobâtonnets d’or sont des particules plasmoniques présentant des propriétés optiques intéressantes. En particulier, la résonance plasmonique de surface localisée (LSPR) sensible à l’environnement local des particules, permet leur utilisation comme transducteurs de phénomènes d’interactions…, Gold nanorods are plasmonic nanoparticles with interesting optical properties. In particular, the localized surface plasmon resonance (LSPR), sensitive to the local environment of the particles, allows their use as transducers of molecular interaction phenomena. This property makes those…

Gold Nanorods for LSPR Biosensing: Synthesis, Coating by Silica, and Bioanalytical Applications

Vincent Pellas, David Hu, Yacine Mazouzi, Yoan Mimoun, Juliette Blanchard, Clément Guibert, Michèle Salmain, Souhir Boujday

Nanoparticles made of coinage metals are well known to display unique optical properties stemming from the localized surface plasmon resonance (LSPR) phenomenon, allowing their use as transducers in various biosensing configurations. While most of the reports initially dealt with spherical gold…

Electrospray ionization: an efficient approach to deposit polymetallic molecular switches onto gold surfaces

Amina Benchohra, Christophe Méthivier, Jessem Landoulsi, David Kreher, Rodrigue Lescouëzec

Electrospray ionization (EI) deposition is proven efficient in obtaining monolayers of a polymetallic charge transfer complex onto gold surfaces. The molecule's integrity is monitored by PM-IRRAS and XPS. This approach broadens the perspective of molecular magnetic switches' deposition,…

Influence of the Ageing and Drying Steps of a CoMoP/γ‐Al2O3 Catalyst onto the Multi‐Scale Molybdenum Active Phase Organization

Candice Cottrez, Séverine Humbert, Anne‐sophie Gay, Elodie Devers, Frédéric de Geuser, Xavier Carrier, Alexandra Chaumonnot

To study the influence of ageing and drying steps onto the multiscale Mo active phase arrangement (i. e. MoS2 slabs and slab aggregates), a series of highly loaded CoMoP/γ-Al2O3 catalysts aged, unaged, dried or freeze-dried were prepared and tested in toluene hydrogenation. Electron Probe Micro…

A comparative study of the catalysis of peptide bonds formation by oxide surfaces

Jean-Francois Lambert, Maguy Jaber, Thomas Georgelin, Lorenzo Stievano

It is well-known that amino acids deposited on some inorganic oxides undergo peptidic condensation. It is seldom realised however that a large diversity of behaviours can be observed in such systems. Here we use the apparently simple case of glycine-non-porous silica as a reference system, in which…

Amphiphilic block copolymer nano-fibers via RAFT-mediated polymerization in aqueous dispersed system

Stephanie Boisse, Jutta Rieger, Khaled Belal, Aurelie Di-Cicco, Patricia Beaunier, Min-Hui Li, Bernadette Charleux

Self-assembled block copolymer nanofibers are attractive materials for multiple applications. We propose here a novel, very simple and straightforward method to prepare polymeric nanofibers at high solids contents directly in water. It is based on an aqueous emulsion polymerization process…
