Layer-by-layer generation of PEG-based regenerable immunosensing surfaces for small-sized analytes

Maria Huebner, Maroua Ben Haddada, Christophe Méthivier, Reinhard Niessner, Dietmar Knopp, Souhir Boujday

Small molecules (haptens) like pharmaceuticals or peptides can serve as targets for antibody binding in competitive immunoassay-based flow-through assays. In this work, a strategy for preparing polyethylene glycol (PEG) coatings for subsequent hapten immobilization on glass-type silica surfaces is…

Different Kinds of Tetrahedral V Species in Vanadium-Containing Zeolites Evidenced by Diffuse Reflectance UV-vis, Raman, and Periodic Density Functional Theory

Anna E. Lewandowska, Miguel A. Banares, Frederik Tielens, Michel Che, Stanislaw Dzwigaj

The combined use of DR-UV-vis and Raman spectroscopies allows one to evidence three kinds of tetrahedral V-V with different structure in V(x)SiBEA zeolite. In all cases, vanadium species possess distorted tetrahedral configuration. At very low vanadium content (0.05 wt %), the majority of…

An Experimental and Theoretical Approach to Investigate the Effect of Chain Length on Aminothiol Adsorption and Assembly on Gold

Erin Bedford, Vincent Humblot, Christophe Méthivier, Claire-Marie Pradier, Frank Gu, Frederik Tielens, Souhir Boujday

Despite the numerous studies on the self-assembled monolayers (SAMs) of alkylthiols on gold, the mechanisms involved, especially the nature and influence of the thiol-gold interface are still under debate. In this work the adsorption of aminothiols on Au(111) surfaces has been studied by using…

Methanol Oxidation to Formaldehyde on VSiBEA Zeolite: A Combined DFT/vdW/Transition Path Sampling and Experimental Study

Diana C. Tranca, Frerich J. Keil, Ionut Tranca, Monica Calatayud, Stanislaw Dzwigaj, Maciej Trejda, Frederik Tielens

Density functional calculations have been performed applying periodic boundary conditions to investigate the oxidation of methanol on vanadium-containing SiBEA zeolite (VSiBEA). Different types of reaction configurations have been set up in conformity with the experimental conditions. Thermodynamic…

A new method for elaborating mesoporous SiO 2 /montmorillonite composite materials

Khalil Tesnime Abou, Chaabene Semy Ben, Boujday Souhir, Blanchard Juliette, Bergaoui Latifa

We report the sol–gel preparation of SiO 2 / montmorillonite composite materials and the investigation of the effect of the amount of clay and the TEOS concentration on the textural and structural properties of the composites. Pre-swelling of the clay with cetyltrimethyl ammonium results in solids…

Deciphering the Adsorption Mechanisms of RGD Subunits: L-Aspartic Acid on Cu(110)

Roberta Totani, Christophe Méthivier, Hervé Cruguel, Claire-Marie Pradier, Vincent Humblot

In this work we present a detailed surface science characterization of L-Aspartic acid adsorption on a Cu(110) surface. We replaced the traditional sublimation method to obtain molecular films by dosing aspartic acid directly from an aqueous solution through an Electrospray Ionization (ESI) device…
