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…

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…

A versatile approach for the immobilization of amines via copper-free "click" reaction between azido self-assembled monolayer and alkynyl Fischer carbene complex. Application to the detection of staphylococcal enterotoxin A antibody

Pratima Srivastava, Amithaba Sarkar, Sudeshna Sawoo, Amarnath Chakraborty, Piyali Dutta, Othman Bouloussa, Christophe Methivier, Claire-Marie Pradier, Souhir Boujday, Michele Salmain

A copper-free "click" reaction between an azido-terminated self-assembled monolayer (SAM) chemisorbed on planar gold-coated glass sensors and an alkynyl Fischer carbene complex yielded functionalized surfaces onto which facile and swift grafting of amine-containing molecules was achieved…

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…

Orientation of a Trametes versicolor laccase on amorphous carbon nitride coated graphite electrodes for improved electroreduction of dioxygen to water

Achraf Blout, Florence Billon, Christophe Calers, Christophe Méthivier, Alain Pailleret, Hubert Perrot, Claude Jolivalt

Amorphous carbon nitride (a-CNx) thin films were used for the first time as electrode materials in the elaboration of biofuel cell cathodes as a consequence of i) the natural presence of amine type functional groups and ii) the ease to generate carboxylic acid groups on their surface with the help…

End-Cretaceous akaganéite as a mineral marker of Deccan volcanism in the sedimentary record

Eric Font, Julie Carlut, Céline Remazeilles, Tamsin A Mather, Anne Nédélec, Jose Mirao, Sandra Casale

An enigmatic chloride-rich iron (oxyhydr)oxide has been recently identified together with mercury anomalies in End-Cretaceous marine sediments coeval with the Deccan Traps eruptions. The mineral was observed in Bidart (France) and Gubbio (Italy), suggesting a widespread phenomenon. However, the…
