Al-Mn-silicate nanobubbles phase as an intermediate in zeolite formation

Amal Bejar, Semy Ben Chaabene, Maguy Jaber, Jean-François Lambert, Latifa Bergaoui

Manganese (II) carbonate, silicic acid and aluminum nitrate were treated hydrothermally at different temperatures (120–210°C) and for different durations (6–72 h) in an aqueous basic medium. Different compositions of starting mixtures were used. The synthetized materials were characterized by…

Impact of nontronite on the evolution of organic molecules at the surface of Mars

Patrice Coll, Olivier Poch, Maguy Jaber, Jean-François Lambert, Thomas Georgelin, Cyril Szopa, Fabien Stalport

Several evidences suggest that early Mars offered favorable conditions for long-term sustaining water. As a consequence, we can assume that in those days, endogenous chemical processes, or even primitive life, may have produced organic matter on Mars. Moreover, exogenous delivery from small bodies…

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…

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…

Bisorganophosphonyl and ‐Organoarsenyl Derivatives of Heteropolytungstates as Hard Ligands for Early‐Transition‐Metal and Lanthanide Cations

Richard Villanneau, Aïcha Ben Djamâa, Lise‐marie Chamoreau, Geoffrey Gontard, Anna Proust

Abstract The coordination properties of bisorganophosphonyl and bisorganoarsenyl derivatives of heteropolytungstates towards lanthanides and early‐transition‐metal cations were studied in organic medium. This new class of vacant polyoxometalate (POM) hybrids proved to conserve coordination sites…

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…

Selective uptake of La3+ ions with polyoxometalates-functionalized mesoporous SBA-15: An EXAFS study

Ourania Makrygenni, Faiza Lilia Bentaleb, Dalil Brouri, Anna Proust, Franck Launay, Richard Villanneau

In this work, mesoporous materials based on inorganic/organic polyoxometalate (POMs) hybrids with the ability of further incorporating heterometallic lanthanum cations were designed. On the basis of the La3+ coordination to vacant organophosphonyle derivatives of POMs previously studied, herein…

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…
