Interaction of proteins with chemically controlled surfaces for biosensor development, Interactions des protéines avec des surfaces chimiquement contrôlées pour le développement de bio-senseurs

Victor Lebec

In this work we studied protein adsorption on chemically well-controlled surfaces. The focus is put on linking physico-chemical properties of surfaces (hydrophobicity/charge) to the structural properties of the adsorbed proteins. To this end, alkyl thiols differing by their end group were used to…, Dans ce travail, nous étudions l’adsorption de protéines sur des surfaces chimiquement contrôlées. Le but est d’établir le lien entre les propriétés physico-chimiques de la surface (hydrophobicité /charge) et la structure physique de protéines. Des couches auto-assemblées de thiols ayant des…

On the physical properties of mixtures of nitrate salts and protic ionic liquids

Pablo Vallet, Silvia Bouzón-Capelo, Trinidad Méndez-Morales, Víctor Gómez-González, Yago Arosa, Raúl de La Fuente, Elena López-Lago, Julio Rodríguez, Luis Gallego, Juan Parajó, Josefa Salgado, Mireille Turmine, Luisa Segade, Oscar Cabeza, Luis Varela

We report a systematic study of the effect of salt concentration and its cation valence on several equilibrium and transport properties of mixtures of the model protic ionic liquid ethylammonium nitrate with monovalent (LiNO3), divalent (Mg(NO3)2 and Ca(NO3)2), and trivalent (Al(NO3)3) salts. These…

The influence of the preparation procedures on the catalytic activity of Fe-BEA zeolites in SCR of NO with ammonia and N2O decomposition

Paweł Boroń, Lucjan Chmielarz, Jacek Gurgul, Kazimierz Łątka, Barbara Gil, Jean-Marc Krafft, Stanislaw Dzwigaj

Three series of Fe-containing BEA zeolites are prepared by two-step postsynthesis (PS), ion exchange (IE) and conventional wet impregnation (Imp) procedures with various Fe content (1.0–4.0 Fe wt.%). In these series of zeolites iron is mainly present as pseudo-tetrahedral Fe(III) as evidenced by…

Role of Water on the Activity of Magnesium Silicate for Transesterification Reactions

Longfei Lin, Damien Cornu, Maya Mounir daou, Cyril Domingos, Virginie Herledan, Jean-Marc Krafft, Guillaume Laugel, Yannick Millot, Hélène Lauron-Pernot

This study aims to reveal how water adsorbed on to a solid can influence its catalytic properties for transesterification in liquid phase. A commercial magnesium silicate was subjected to a range of thermal pretreatments and used for the transesterification of ethyl acetate with methanol.…

Monitoring of the Plasmon Resonance of Gold Nanoparticles in Au/TiO2 Catalyst under Oxidative and Reducing Atmospheres

Yves Borensztein, Laurent Delannoy, Anis Djedidi, Ruben G. Barrera, Catherine Louis

Diffuse optical reflectance of Au/TiO2 powder catalysts, prepared by the deposition-precipitation method, is measured in the UV-visible range in controlled atmosphere. An intense optical absorption observed around 550 nm is interpreted by the excitation of plasmon resonances in the 4 nm gold…

Chiral Recognition of l-Gramicidine on Chiraly Methionine-Modified Au(111)

Vincent Humblot, Claire-Marie Pradier

A chiral pentadecapeptide, l-gramicidine, has been shown to undergo specific adsorption onto gold surfaces modified by chiral amino acids, d- and l-methionine, upon adsorption in the liquid phase. There is a chiral recognition only between the slightly anionic l-peptide and the l-modified surface…

A New Nanocomposite: L-DOPA/Laponite

Maguy Jaber, Jean-Francois Lambert

A simple procedure is reported to obtain original nanocomposite materials combining the smectite Laponite and melanin-like polymers. Aq. polymn. of L-DOPA is considerably accelerated in the presence of suspended Laponite particles, and its mechanism is significantly modified with respect to…
