Layer-by-Layer Assembly of Nanosized Membrane Fractions for the Assessment of Cytochrome P450 Xenobiotic Metabolism

Paul Quantin, Elodie Colaço, Karim El Kirat, Christophe Egles, Hervé Ficheux, Jessem Landoulsi

Herein, we report the use of sequential layer-by-layer (LbL) assembly to design nanostructured films made of recombinant bacterial membrane fractions (MF), which overexpress cytochrome P450 (CYP) and cytochrome P450 reductase. The ability to incorporate MF in LbL multilayered films is demonstrated…

Development of a hybrid coating associating biomimetic hydroxyapatite and natural antibiotics with antibacterial properties, Développement d’un revêtement hybride aux propriétés antibactériennes associant hydroxyapatite biomimétique et antibiotiques naturels

Estelle Palierse

This thesis aims to develop a hybrid coating based on biomimetic hydroxyapatite and natural antibacterial molecules, with the goal to add antibacterial properties and enhance the osseointegration of titanium (Ti6Al4V) implants. Four natural biologically active molecules (BAMs) were tested,…, Cette thèse porte sur l’élaboration de revêtements de surface hybrides composés d’hydroxyapatite biomimétique et de molécules antibactériennes naturelles, dans le but d’ajouter des propriétés antibactériennes et d’améliorer l’ostéointégration d’implants en titane (Ti6Al4V). Quatre molécules…

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…

HgTe Nanocrystal Inks for Extended Short‐Wave Infrared Detection

Bertille Martinez, Julien Ramade, Clément Livache, Nicolas Goubet, Audrey Chu, Charlie Gréboval, Junling Qu, William L Watkins, Loic Becerra, Erwan Dandeu, Jean Louis Fave, Christophe Méthivier, Emmanuelle Lacaze, Emmanuel Lhuillier

Short‐wave infrared (IR) detection is currently driven by InGaAs technology which has limited the perspective of cost effectiveness and consequently slows the development of IR sensors. Since organic electronics are ineffective in this wavelength range, an alternative to conductive polymers is the…

Organo-NOx formation-decomposition as the origin of the changes in the low temperature NO-TPD profile in the presence of n-decane on Ag/γ-Al2O3

Kinga Malinger, Juliette Blanchard, Rachel P. Doherty, Cyril Thomas

The NOx desorption profiles obtained in O2-He and n-C10-O2-He were compared on γ-Al2O3 and Ag/γ-Al2O3. On Ag/γ-Al2O3, the low-temperature NOx desorption profiles obtained in n-C10-O2-He were significantly different from those obtained in O2-He. In particular, at 190-220 °C excess release of NO,…

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…

Solvent effects on the vibrational spectrum of 3-hydroxyflavone

Ari Paavo Seitsonen, Abdenacer Idrissi, Stefano Protti, Alberto Mezzetti

3-hydroxyflavone (3HF) is a widely studied molecule that acts as a simplified prototype of biological, more complex flavonoids. Its solvation mechanism is still under investigation. Here we report a joint experimental and simulation study of the vibrational properties of 3HF in gas phase and in…

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…
