Piezoelectricimmunosensor for direct and rapiddetection of staphylococcal enterotoxin A (SEA) at the ng level

Michèle Salmain, Mahsa Ghasemi, Souhir Boujday, Jolanda Spadavecchia, Marie-Clarisse Techer, Florence Val, Vincent Le Moigne, M. Gautier, Romain Briandet, Claire-Marie Pradier

A direct, label-free immunosensor was designed for the rapiddetection and quantification of staphylococcal enterotoxin A (SEA) in buffered solutions using quartz crystal microbalance with dissipation (QCM-D) as transduction method. The sensing layer including the anti-SEA antibody was constructed…

Silver species reduction upon exposure of Ag/Al2O3 catalyst to gaseous ethanol: An in situ Quick-XANES study

Elie Sayah, Camille La Fontaine, Valérie Briois, Dalil Brouri, Pascale Massiani

The evolution of supported silver species of a pre-calcined Ag/Al2O3 catalyst was monitored upon thermal treatment under an air flow enriched with 3000 ppm of ethanol (EtOH) using transmission electron microscopy and UV-visible and X-ray absorption spectroscopies. A special focus is put on the…

Specificinteractions of functionalisedgoldsurfaces with ammonium perchlorate or starch; towards a chemical cartography of their mixture

D. Mercier, C. Mercader, S. Quere, Lionel Hairault, Christophe Methivier, Claire-Marie Pradier

By functionalising gold samples, planar wafers or AFM tips, with an acid- or an amino acid-terminated thiols, mercaptoundecanoic acid (MUA) and homocystein (H-Cyst) respectively, we were able to differentiate the interactions with ammonium perchlorate (AP) and starch (S), two components of a…

Effect of equal channel angular extrusion on wear and corrosion behavior of the orthopedic Ti-13Nb-13Zr alloy in simulated body fluid

K.S. Suresh, M. Geetha, C. Richard, Jessem Landoulsi, H. Ramasawmy, S. Suwas, R. Asokamani

We report investigations on the texture, corrosion and wear behavior of ultra-fine grained (UFG) Ti-13Nb-Zr alloy, processed by equal channel angular extrusion (ECAE) technique, for biomedical applications. The microstructure obtained was characterized by X-ray line profile analysis, scanning…

The influence of C1 and C2 organic reducing agents on catalytic properties of Co(II)-single site BEA zeolite in SCR of NO

Janusz Janas, Wojciech Rojek, Stanislaw Dzwigaj

CoSiBEA zeolite with 0.9 wt.% Co is prepared in acidic (pH = 2.5) condition by a two-step postsynthesis method which allows to incorporate cobalt into framework zeolite as isolated tetrahedral Co(II) species, as evidenced by XRD and diffuse reflectance UV-vis. As obtained Co(II)-single site zeolite…

Chromium sites in zeolite framework: Chromyl or chromium hydroxyl groups?

Frederik Tielens, Mazharul M. Islam, Gabriella Skara, F. de Proft, Tetsuya Shishido, Stanislaw Dzwigaj

A combined experimental and ab initio periodic DFT calculation on the structure and stability of different chromium-substituted zeolite models are presented. Experimental investigation by XRD, FT-IR and UV-vis show the presence of chromium in SiBEA zeolite. The favorable chromium sites are…

Influence of the preparation procedure on the nature and environment of vanadium in VSiBEA zeolite: XRD, DR UV-vis, NMR, EPR and TPR studies

Rafal Baran, Yannick Millot, Thomas Onfroy, Frédéric Averseng, Jean-Marc Krafft, Stanislaw Dzwigaj

Two series of VxSiBEA(I) and VxSiBEA(II) zeolites have been prepared by a two-steps postsynthesis method which consists, in the first step, in the dealumination of TEABEA zeolite by two different procedures to obtain SiBEA(I) and SiBEA(II) zeolites and then, in the second step, in contacting the…

Nanoparticules d’or pour les biocapteurs : lecture optique de la reconnaissance moléculaire

Souhir Boujday, Michèle Salmain

Les propriétés extraordinaires des nanoparticules d’or et/ou d’argent en ont fait des objets courtisés par les scientifiques toutes disciplines confondues. L’intensité de leur couleur ainsi que leur grande sensibilité optique au milieu environnant en font de puissants transducteurs pour les…

Biomineralization in Barnacle Base Plate in Association with Adhesive Cement Protein

Sunyoung Hur, Christophe Méthivier, Axel Wilson, Michèle Salmain, Souhir Boujday, Ali Miserez

The interaction of incident light with noble metal nanoparticles engenders a fascinating phenomenon known as localized surface plasmon resonance (LSPR). This results in the presence of single or multiple intense absorption bands in the visible to near-infrared spectral range whose position is…
