Gold Colloid-Nanostructured Surfaces for Enhanced Piezoelectric Immunosensing of Staphylococcal Enterotoxin A

Maroua Ben Haddada, Michèle Salmain, Souhir Boujday

We describe the use of gold nanoparticles (AuNP) as a nanostructuring agent on quartz crystal sensor chips to engineer staphylococcal enterotoxin A (SEA) piezoelectric biosensors with amplified response. AuNPs were assembled on gold- or silicon-coated quartz crystal sensor chips by a wet chemistry…

Glutamic Acid Adsorption and Transformations on Silica

Meryem Bouchoucha, Maguy Jaber, Thomas Onfroy, Jean-François Lambert, Xue Baiyi

We report here on the adsorption and deposition of l-glutamic acid (Glu) on an amorphous silica and its subsequent thermal transformations. When adsorbed from aqueous solutions, Glu only has a low affinity for the silica surface but at high concentrations the adsorbed molecules serve as nuclei for…

Highly Conductive Tungsten Suboxide Nanotubes

Cécile Huez, Maxime Berthe, Florence Volatron, Jean-Michel Guigner, Dalil Brouri, Lise-Marie Chamoreau, Benoît Baptiste, Dominique Vuillaume, Anna Proust

We demonstrate a high electron conductivity (> 10^2 S/cm and up to 10^3 S/cm) of tungsten suboxide W18O(52.4-52.9)(or equivalently WO(2.91-2.94)) nanotubes (2 to 3 nm in diameter, ca. micrometer long). The conductivity is measured in the temperature range 120 to 300K by a four probe scanning…

Stability and degradation of PEO₂₀PPO₇₀PEO₂₀ triblock copolymers in mesostructured silica

Brindusa Dragoi, Guillaume Laurent, Sandra Casale, Taissire Benamor, Bénédicte Lebeau, Cédric Boissière, François Ribot, Mohamed Selmane, Patrick Schmidt, David Kreher, Anne Davidson

Organic−inorganic hybrid mesostructured silicas are prepared, without stirring (at pH = 0.0) and with stirring (at pH = 0.6) to obtain isolated and gyroidal-like attached silica grains with incorporated triblock P123 poly (ethylene oxide)-poly (propylene oxide)–poly (ethylene oxide) copolymers.…

Strategies for Antimicrobial Peptides Immobilization on Surfaces to Prevent Biofilm Growth on Biomedical Devices

Mathieu Nicolas, Bruno Beito, Marta Oliveira, Maria Tudela Martins, Bruno Gallas, Michèle Salmain, Souhir Boujday, Vincent Humblot

Nosocomial and medical device-induced biofilm infections affect millions of lives and urgently require innovative preventive approaches. These pathologies have led to the development of numerous antimicrobial strategies, an emergent topic involving both natural and synthetic routes, among which…

The Influence of TiO2 Nanoparticles Morphologies on the Performance of Lithium-Ion Batteries

Wenpo Luo, Juliette Blanchard, Yanpeng Xue, Abdelhafed Taleb

Anode materials based on the TiO2 nanoparticles of different morphologies were prepared using the hydrothermal method and characterized by various techniques, such as X-ray diffraction (XRD), field-emission scanning electron microscopy (FE-SEM), and N2 absorption. The TiO2 nanoparticles prepared…

Covalent shaping of polyoxometalate molecular films onto ITO electrodes for charge trapping induced resistive switching

Raphaël Salles, Wei Church Poh, Maxime Laurans, Florence Volatron, Antoine Miche, Sandra Alves, Christian Carino, Ludovic Tortech, Guillaume Izzet, Pooi See Lee, Anna PROUST

As nano-sized molecular oxides, polyoxometalates (POMs) hold great promise in non-volatile memory materials based on redox-active molecules. Materials processed from solution, by drop-casting, by embedding POMs in polymers, or using Layer-by-Layer deposition techniques have thus been reported and…
