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…

Revisiting active sites in heterogeneous catalysis: Their structure and their dynamic behaviour

Jacques C. Vedrine

This short review article aims at revisiting the description of active sites in heterogeneous catalysis on solid surfaces and their role in catalyst activity and selectivity. Special emphasis is brought to: (i) structure of the solid surface; (ii) importance of active site isolation on the surface…

Elaboration, characterization and properties of silica-based single-site heterogeneous photocatalysts

M. Che, K. Mori, H. Yamashita

This study concerns single-site heterogeneous photocatalysts, composed of isolated transition metals ions (single-sites) dispersed on silica-based supports, which can be used as photocatalysts. The first part gives the definition of single-site heterogeneous catalysts. The main difficulty to…

Modification of TiO2 by bimetallic Au–Cu nanoparticles for wastewater treatment

Zibin Hai, Nadia El Kolli, Daniel Bahena Uribe, Patricia Beaunier, Miguel José-Yacaman, Jackie Vigneron, Arnaud Etcheberry, Sébastien Sorgues, Christophe Colbeau-Justin, Jiafu Chen, Hynd Remita

Au, Cu and bimetallic Au–Cu nanoparticles were synthesized on the surface of commercial TiO2 compounds (P25) by reduction of the metal precursors with tetrakis(hydroxymethyl) phosphonium chloride (THPC) (0.5% in weight). The alloyed structure of Au–Cu NPs was confirmed by HAADF-STEM, EDS, HRTEM and…

Tunable physics through coordination chemistry: formation on oxide surface of Ti and Al chelates with 3-hydroxyflavone capable of electron injection and light emission

Getachew Solomon, Anton Landström, Silvia Rotta Loria, Eleonora Bolli, Alberto Mezzetti, Anna Facibeni, Sandro Cattarin, Alessio Mezzi, Stefano Protti, Saulius Kaciulis, Margherita Zavelani-Rossi, Isabella Concina

The optoelectronic features of 3-hydroxyflavone (3HF) self-assembled on the surface of an n-type semiconducting metal oxide (TiO2) and an insulator (Al2O3) are herein investigated. 3HF molecules use the coordinatively unsaturated metal ions present on the oxide surface to form metal complexes,…

Adsorption of bromothymol blue (BTB) dye using four zeolites as adsorbent

Imene Benchikh, Mohamed Serier, Franck Launay, Fatiha Djafri, Affaf Tabti

This study examined adsorption of anionic dye on four zeolitic materials incorporated (VS-1, CuZSM-5) and not incorporated into metals (S-1, ZSM-5). The adsorption of the bromothymol blue (BTB) dye on the four adsorbents was analysed using isotherm models Langmuir, Freundlich, and Temkin. Two…, U ovoj je studiji ispitivana adsorpcija anionskih bojila na četiri zeolitska materijala inkorporirana (VS-1, CuZSM-5) i neinkorporirana (S-1, ZSM-5) u metale. Adsorpcija indikatora bromtimol modro (BTB) na četiri adsorbenta analizirana je izotermnim modelima Langmuir, Freundlich i Temkin. Također…

Immobilization of atrazine on gold, a first step towards the elaboration of an indirect immunosensor, characterised by XPS and FT-IRRAS

Michèle Salmain, Natahlie Fischer-Durand, Céline Roche, Claire-Marie Pradier

As part of our long-term goal to design a novel type of immunosensor based on IR transduction, we devised two strategies to immobilize derivatives of the herbicide atrazine on the surface of planar gold substrates. Both strategies take advantage of the well-known formation of self-assembled…
