Stability of Binary SAMs Formed by omega-Acid and Alcohol Functionalized Thiol Mixtures

Frederik Tielens, Vincent Humblot, Claire-Marie Pradier, Monica Calatayud, Francesc Illas

A simple model is presented to describe the mixing process of acid- and alcohol-terminated thiol self-assembled monolayers (SAMs) on Au(111). It was found that the low-concentration acid-terminated SAMs are enriched in acid thiol compared with the original solution from which the SAM is made. Due…

Direct quantification of surface coverage of antibody in IgG-Gold nanoparticles conjugates

Lu Zhang, David Hu, Michèle Salmain, Bo Liedberg, Souhir Boujday

It is of paramount importance to be able to accurately quantify surface coverage of antibodies on gold nanoparticles (AuNP) so as to optimise the sensitivity of AuNP-based immunosensors. Herein, we developed a fluorescence-based method to directly quantify rabbit immunoglobulin G (IgG) used as…

Peptide-oxide binding mechanism : exploring the role of surfaces and interfaces at the origins of life, Mécanismes de liaison peptide-oxyde : étude du rôle des surfaces et des interfaces aux origines de la vie

Joanne Lê-Chesnais

This doctoral work focused on the study of amino acid (AA) adsorption on mineral substrates, in the context of prebiotic chemistry and the origins of life. These systems exhibit a reactivity that promotes the formation of oligopeptides, essential molecular precursors of early life, yet the detailed…, Cette thèse a porté sur l'étude de l'adsorption d'acides aminés (AA) sur supports minéraux, dans le cadre des recherches sur les origines de la vie. Ces systèmes présentent une réactivité propice à la formation d'oligopeptides, premières briques du vivant, mais les mécanismes d…

Walking peptide on Au(110) surface: Origin and nature of interfacial process

V. Humblot, A. Tejeda, J. Landoulsi, A. Vallée, A. Naitabdi, Ahmed Taleb, C.-M. Pradier

IGF tri-peptide adsorption on Au(110)-(1 × 2) under Ultra High Vacuum (UHV) conditions has been investigated using surface science techniques such as synchrotron based Angle Resolved X-ray Photoemission Spectroscopy (AR-PES or AR-XPS), Low Energy Electron Diffraction (LEED) and Scanning Tunnelling…

Theoretical and experimental study of the adsorption of neutral glycine on silica from the gas phase

Claire Lomenech, Gregoire Bery, Dominique Costa, Lorenzo Stievano, Jean-François Lambert

The adsorption of neutral glycine onto amorphous silica was investigated both theoretically and experimentally. DFT calculations were performed at the BLYP-631++G** level using a cluster approach. Several possible configurations involving the formation of H-bonds between glycine and one, two or…

Design of simple salophen chromium complexes for a two-steps oxidative carboxylation of styrene with CO2 and O2

Matthieu Balas, Richard Villanneau, Franck Launay

In this work, chromium(III) Salophen complexes bearing tertiary dimethyl or diethyl amino substituents were synthesized and tested as homogeneous co-catalysts associated with n-Bu 4 NBr for the cycloaddition of CO 2 on styrene epoxide under 11 bar of CO 2. Full conversion of styrene oxide into…

Design of Mixed PEO/PAA Brushes with Switchable Properties Toward Protein Adsorption

M.F. Delacroix, G.L. Huet, T. Conard, S. Demoustier-Champagne, Filip E. Du Prez, Jessem Landoulsi, C.C. Dupont-Gillain

Adsorption of proteins at interfaces is an ubiquitous phenomenon of prime importance. Layers of poly(ethylene oxide) (PEO) are widely used to repel proteins. Conversely, proteins were shown to adsorb deeply into brushes of poly(acrylic acid) (PAA), and their subsequent partial release could be…
