Two-Dimensional Layers of Colloidal CdTe Quantum Dots: Assembly, Optical Properties, and Vibroelectronic Coupling

Thomas Noblet, Souhir Boujday, Christophe Methivier, Marie Erard, Julie Hottechamps, Bertrand Busson, Christophe Humbert

The manufacturing of silica platforms functionalized by CdTe quantum dots (QDs) of 3.4 nm diameter through (3-aminopropy)triethoxysilane (APTES) aliphatic organosilanes is performed to preserve QDs excitonic properties after their transfer from colloidal solutions to surfaces at ambient air. In…

Catalytic activity and thermostability of enzymes immobilized on silanized surface: Influence of the crosslinking agent

Nesrine Aissaoui, Jessem Landoulsi, Latifa Bergaoui, Souhir Boujday, Jean-François Lambert

In this work, we investigate the influence of crosslinkers on the operational and heat stability of immobilized enzymes on a silanized silicon surface. To this end, glucose-6-phosphate dehydrogenase (G6PDH), a model multimeric enzyme, was attached through bifunctional crosslinkers able to bind…

Investigation of an Allergen Adsorption on Amine- and Acid-Terminated Thiol Layers: Influence on Their Affinity to Specific Antibodies

P. Thebault, Souhir Boujday, Helene Senechal, Claire-Marie Pradier

This work describes the controlled immobilization of a recognized allergen, beta-lactoglobulin, onto gold transducers with the aim of optimizing the elaboration of a biosensor directed against allergen-produced antibodies. This protein was immobilized on both amine- and acid-terminated thiol self-…

Biosensing Extracellular Vesicle Subpopulations in Neurodegenerative Disease Conditions

Yacine Mazouzi, Fadoua Sallem, Francesca Farina, Alexis Loiseau, Natayme Rocha Tartaglia, Morgane Fontaine, Atul Parikh, Michèle Salmain, Christian Neri, Souhir Boujday

Extracellular vesicles (EVs) are secreted nanoparticles that are involved in intercellular communication and that modulate a wide range of biological processes in normal and disease conditions. However, EVs are highly heterogeneous in terms of origin in the cell, size, and density. As a result,…

Silane Layers on Silicon Surfaces: Mechanism of Interaction, Stability, and Influence on Protein Adsorption

Nesrine Aissaoui, Latifa Bergaoui, Jessem Landoulsi, Jean-François Lambert, Souhir Boujday

In this work the mechanism of (3-aminopropyl)triethoxysilane (APTES) interaction with silicon surfaces is investigated at the molecular level. We studied the influence of experimental parameters such as time, temperature, and concentration on the quality of the APTES layer in terms of chemical…

Design and Analytical Performances of a Diclofenac Biosensor for Water Resources Monitoring

Yacine Mazouzi, Antoine Miche, Alexis Loiseau, Bruno Beito, Christophe Méthivier, Dietmar Knopp, Michèle Salmain, Souhir Boujday

Because the broadly consumed pain killer diclofenac (DCF) is a recognized pollutant, monitoring of its concentration is routinely performed in surface waters. As a valuable alternative to chromatographic and immunochemical assays, we developed a piezoelectric immunosensor to quantify DCF, first in…

EIS investigation of zinc dissolution in aerated sulphate medium. Part II: zinc coatings

Chantal Cachet, F. Ganne, Suzanne Joiret, Georges Maurin, J. Petitjean, Vincent Vivier, Robert Wiart

The kinetics of anodic dissolution and corrosion of zinc coatings deposited onto steel sheet either by electrodeposition or by hot dipping are investigated by electrochemical impedance spectroscopy in aerated sulfate medium. The results are compared with those obtained previously on pure bulk zinc…
