Building of an immunosensor : how can the composition and structure of the thiol attachment layer affect the immunosensor efficiency ?

Elisabeth Briand, Michèle Salmain, Jean-Marie Herry, Hubert Perrot, Chantal Compere, Claire-Marie Pradier

Immunosensors, based on the immobilsation of model rabbit antibodies on a mixed self assembled monolyaers and Protein A as a linking agent on gold transducers, were elaborated and characterised at each step by Modulated polarisation- Infrared Spectroscopy (PM-IRRAS) and punctually by Atomic Force…

ADSORPTION ON STAINLESS STEEL SURFACES OF BIOSURFACTANTS PRODUCED BY GRAM-NEGATIVE AND GRAM-POSITIVE BACTERIA : CONSEQUENCE ON THE BIOADHESIVE BEHAVIOR OF PATHOGENIC STRAINS.

Thierry Meylheuc, Christophe Méthivier, Margareth Renault, Jean-Marie Herry, Claire-Marie Pradier, Marie-Noëlle Bellon-Fontaine

The ability of adsorbed biosurfactants (Pf and Lb) obtained from gram negative bacterium (Pseudomonas fluorescens) or gram positive bacterium (Lactobacillus helveticus) to inhibit adhesion of four listerial strains to stainless steel was investigated. These metallic surfaces were characterized…

Surface response methodology for the study of supported membrane formation.

C. Rossi, Elisabeth Briand, P. Parot, Michaël Odorico, Joël Chopineau

We report on the investigations of the formation of the tethered lipid bilayer by vesicle deposition on amine-functionalized surfaces. The tethered bilayer was created by the deposition of egg-PC vesicles containing 1,2-distearoyl-sn-glycero-3-phosphoethanolamine-poly-(ethyleneglycol)-N-…

Study of the use of fluidized bed plasma reactors for the treatment of alumina supported palladium catalyst: Application for SCR NOx by CH4 in stationary sources

Marjorie Foix, Cedric Guyon, Michael Tatoulian, Patrick da Costa

Calcination is an important step in catalyst synthesis. This work examd. plasma treatment as an alternative to calcination, since it is a more energy efficient process. A radio frequency, fluidized bed plasma reactor was used for the pretreatment process with different gas mixts. (Ar and Ar/O2…

Insight into the structure and localization of the titania overlayer in TiO2-coated SBA-15 materials

Fu-Xiang Zhang, Xavier Carrier, Jean-Marc Krafft, Yu-Ji Yoshimura, Juliette Blanchard

Titania-coated SBA-15 materials (Ti-SBA-n with n = 1-4) were synthesized by successive grafting of titanium isopropoxide in iso-propanol. The investigation of the nature and localization of the TiO2 overlayer allowed us to conclude that there was formation of very small (UV-visible, EXAFS, XANES),…

Polyol synthesis and magnetic study of Mn3O4 nanocrystals of tunable size

Lorette Sicard, Jean-Marc Le Meins, Christophe Methivier, Frederic Herbst, Souad Ammar

Nanosized manganese oxide particles were prepd. by the so-called polyol process. The av. diam. of the particles was controlled by the growth time. XRD, TEM and x-ray photon spectroscopy (XPS) show that the particles are well crystd., pure, stoichiometric Mn3O4 single crystals of uniform size…

Bioengineering of stainless steel surface by covalent immobilization of enzymes. Physical characterization and interfacial enzymatic activity

Anne Caro, Vincent Humblot, Christophe Methivier, Michel Minier, Lucica Barbes, Joachim Li, Michele Salmain, Claire-Marie Pradier

Two hydrolytic enzymes, namely lysozyme and trypsin, were covalently immobilized onto stainless steel surfaces using wet chemistry processes. The immobilization strategy took advantage of the spontaneous physisorption of the polymer poly(ethylene imine) (PEI) onto stainless steel to yield a firmly…

Exhaust gas recirculation for on-board hydrogen production by isooctane reforming: Comparison of performances of metal/ceria-zirconia based catalysts prepared through pseudo sol-gel or impregnation methods are described

Emmanuelle Ambroise, Claire Courson, Anne-Cecile Roger, Alain Kiennemann, Gilbert Blanchard, Severine Rousseau, Xavier Carrier, Eric Marceau, Camille La Fontaine, Francoise Villain

Isooctane reforming under conditions which are set by exhaust gas can be used to generate H on-board. Isooctane reforming reactivity tests have been performed with bimetallic catalysts Co-noble metal/ceria-zirconia, prepd. either by insertion of transition metal in a ceria-zirconia matrix, either…

Highly porous and monodisperse magnetic silica beads prepared by a green templating method

Sebastien Abramson, Clementine Meiller, Patricia Beaunier, Vincent Dupuis, Laurent Perrigaud, Agnes Bee, Valerie Cabuil

We describe the prepn. of magnetic silica nanocomposite millimetric beads using alginate as a green biopolymer template. The simple and soft method which is used here is particularly suitable since the alginate template allows a multiscale control of the structure of the material, both its morphol…

Detailed crystal chemistry and iron topochemistry of asbestos occurring in its natural setting: A first step to understanding its chemical reactivity

A. Pacella, G. B. Andreozzi, Jeanine Fournier

Five samples of tremolite asbestos from Italy and USA were fully characterized by ICP-MS, SEM, EMPA, FT-IR, MS, XRPD, to correlate crystal chemistry with chemical reactivity. Iron topochemistry was investigated in detail, due to the role of Fe in the aetiology of respiratory inflammatory diseases.…
