Binding mechanism of oligopeptides on solid surface: assessing the significance of single-molecule approach

Joanne Lê-Chesnais, Marie Steffenhagen, Christophe Méthivier, Dominique Costa, Daniela Rodriguez, Jean-François Lambert, Emmanuel Maisonhaute, Jessem Landoulsi

This paper addresses the complementarity and potential disparities between single-molecule and ensemble-average approaches to probe the binding mechanism of oligopeptides on inorganic solids. Specifically, we explore the peptide/gold interface owing to its significance in various topics and its…

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…

Bifunctional Polyoxometalates for Planar Gold Surface Nanostructuration and Protein Immobilization

Dimitri Mercier, Souhir Boujday, Cyrine Annabi, Richard Villanneau, Claire-Marie Pradier, Anna Proust

Surface nanostructuration was successfully achieved by binding the polyoxometalate (POM) (NBu4)3[PW11O39{(SiC6H4NH2)2O}] covalently onto planar gold surfaces. To do so, POMs functionalized with two terminal amino groups were synthesized and reacted with a mercaptoundecanoic acid self-assembled…

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,…

La Recherche en Chimie aux Frontières de la Connaissance

Dominique Massiot, Claire-Marie Pradier, Jacques Maddaluno, Jean-François Tassin, Joël Moreau, Mehran Mostafavi, Anne Imberty, Pascal Breuilles, Catherine Larroche

L’Unité Mixte de Recherche est la brique élémentaire, souple et pérenne d’un paysage de la recherche en évolution rapide. De nombreux dispositifs viennent structurer l’activité de ces équipes pour faire émerger des pôles de recherche, consolider le maillage des réseaux nationaux, identifier les…, Mixed research units are building blocks, flexible but permanent, in rapidly evolving fields of research. Several measures shape the activities of research teams and thus give rise to “poles of research”. They also help consolidate national networks, identify strong points, boost the sharing of top…

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…
