Simple procedure for vacant POMs-stabilized palladium (0) nanoparticles in water: structural and dispersive effects of lacunary polyoxometalates

R. Villanneau, A. Roucoux, P. Beaunier, D. Brouri, A. Proust

Metallic palladium nanoparticles have been generated by hydrogenation with H2 of solutions of several non organometallic Pd II-derivatives of heteropolytungstates, at ambient temperature and atmospheric pressure. These nanoparticles have been characterized by various techniques: 31 P NMR and Raman…

Covalent Grafting of Organic–Inorganic Polyoxometalates Hybrids onto Mesoporous SBA-15: A Key Step for New Anchored Homogeneous Catalysts

Richard Villanneau, Asma Marzouk, Yan Wang, Aicha Ben Djamaa, Guillaume Laugel, Anna Proust, Franck Launay

Covalent grafting of heteropolyanions hybrids B,α-[AsIIIW9O33{P(O)(CH2CH2CO2H)}2]5- on 3-aminopropyle functionalized SBA-15 has been achieved through the formation of peptide bonds. The covalent link has been confirmed by using IR and 13C CP MAS NMR spectroscopies. Electrostatic interactions…

Silica-coated gold nanorods biofunctionalization for localized surface plasmon resonance (LSPR) biosensing

Vincent Pellas, Fadoua Sallem, Juliette Blanchard, Antoine Miche, Sara Martinez Concheso, Christophe Méthivier, Michèle Salmain, Souhir Boujday

We introduce here the engineering of nanobiosensors designed from gold nanorods coated with an ultrathin layer of silica (AuNR@SiO2) and biofunctionalized with antibodies for the Localized Surface Plasmon Resonance (LSPR) biosensing of proteins. Despite the outstanding properties of AuNRs, their…

Gold Nanorod Coating with Silica Shells Having Controlled Thickness and Oriented Porosity: Tailoring the Shells for Biosensing

Vincent Pellas, Juliette Blanchard, Clément Guibert, Jean-Marc Krafft, Antoine Miche, Michèle Salmain, Souhir Boujday

The coating of gold nanorods with a silica shell (AuNR@SiO2) is an effective way to extend their use in a wide variety of biomedical applications. A silica shell offers numerous advantages as it provides more stability, frees the surface from toxic cetyltrimethylammonium bromide (CTAB), and…

Design and Optimization of a Magneto-Plasmonic Sandwich Biosensor for Integration within Microfluidic Devices

Mona Soroush, Walid Ait Ait Mammar, Axel Wilson, Hedayatollah Ghourchian, Michèle Salmain, Souhir Boujday

We designed a magneto-plasmonic biosensor for the immunodetection of antigens in minute sample volume. Both spherical gold nanoparticles (AuNP) and magnetic beads (MB) were conjugated to goat anti-rabbit IgG antibody (Ab) capable of recognizing a model target, rabbit IgG (rIgG). The AuNP…

Mesoporous materials from zeolite seeds as supports for nickel tungsten sulfide active phases Part 1. Characterization and catalytic properties in hydrocracking reactions

Shuangqin Zeng, Juliette Blanchard, Michèle Breysse, Dadong Li, Hong Nie, Yahua Shib, Xintian Su

MCM-41 aluminosilicate mesostructures (Si/Al = 18) with hexagonal long-range order were assembled from protozeolitic nanoclusters (zeolite seeds) that normally nucleate the crystn. of b-zeolite (BEA). Depending on the duration of the thermal treatment leading to the zeolite seeds, different acidic…
