Surface IR immunosensors for label-free detection of benzo[a]pyrene

Souhir Boujday, Soumaya Nasri, Michele Salmain, Claire-Marie Pradier

Polycyclic aromatic hydrocarbons (PAHs) are a family of contaminants originating from the incomplete combustion of organic compounds, present in the urban air, water, soil and also foodstuff. Due to their recognised carcinogenicity, their concentration in urban air is routinely monitored and…

Smartphone-assisted plasmonic biosensors for rapid on-site detection of foodborne pathogens and allergens

Walid Ait Mammar, Axel Wilson, Antoine Miche, Thomas Kuntzel, Michèle Salmain, Souhir Boujday

We report the design of a smartphone-assisted plasmonic immunosensor and its application to the detection of several food contaminants, namely staphylococcal enterotoxin A (SEA), bovine β-lactoglobulin (BLG), and hen egg white lysozyme (LYSO). Comprehensive characterization of antibodies was…

Spiky gold shells on magnetic particles for DNA biosensors

Erin Bedford, Souhir Boujday, Claire-Marie Pradier, Frank Gu

Combined separation and detection of biomolecules has the potential to speed up and improve the sensitivity of disease detection, environmental testing, and biomolecular analysis. In this work, we synthesized magnetic particles coated with spiky nanostructured gold shells and used them to…

A fullerene helical peptide: synthesis, characterization and formation of self-assembled monolayers on gold surfaces

Houssein Nasrallah, Jad Rabah, Van Bui-Thi-Tuyet, Krystyna Baczko, Hélène Fensterbank, Flavien Bourdreux, Anne-Marie Goncalves, Valérie Declerck, Souhir Boujday, Vincent Humblot, Karen Wright, Anne Vallée, Emmanuel Allard

The synthesis of a C60-peptide using "clickable" fullerene and peptide derivatives is described. The peptide is composed of a repeating sequence of -aminoisobutyric acid (Aib) and two L-Alanine (Ala) residues, promoting the formation of a helical conformation, which has been confirmed by…

Revealing the Interplay between Adsorbed Molecular Layers and Gold Nanoparticles by Linear and Nonlinear Optical Properties

Laetitia Dalstein, Maroua Ben Haddada, Grégory Barbillon, Christophe Humbert, Abderrahmane Tadjeddine, Souhir Boujday, Bertrand Busson

Gold nanoparticles (AuNPs) chemically grafted on substrates are widely used as sensors due to their plasmonic properties. The efficiency and robustness of such sensors strongly depend on the molecular sublayer structure, which influences the distribution of AuNPs, and therefore the plasmonic…

Conception de systèmes catalytiques hétérogènes chimioenzymatiques pour l'époxydation, Conception of heterogeneous chemioenzymatic catalysts for epoxydation

Noémie Balistreri

L'objectif de ce travail est de développer un système catalytique hétérogène pour l'époxydation en utilisant directement O2 de l'air plutôt que H2O2 commercial. La stratégie adoptée a été de coupler la production in situ de H2O2, catalysée par la glucose oxydase (GOx), avec un…, The objective of this work was to develop an heterogeneous catalyst system supplied by dioxygen, rather than commercial H2O2, in order to carry out epoxidation reactions. Our strategy was to couple the in situ production of H2O2, catalyzed by glucose oxidase (GOx), with a Ti-based catalyst. The…

Heterogeneous Partial (amm) Oxidation and Oxidative Dehydrogenation Catalysis on Mixed Metal Oxides

Jacques C. Védrine

This paper presents an overview of heterogeneous partial (amm)oxidation and oxidative dehydrogenation (ODH) of hydrocarbons. The review has been voluntarily restricted to metal oxide-type catalysts, as the partial oxidation field is very broad and the number of catalysts is quite high. The main…

Synthèse prébiotique de Ribonucléotides sur des surfaces minérales, Prebiotic synthesis of Ribonucleotides on mineral surfaces

Mariame Akouche

Dans le contexte prébiotique du " monde ARN ", les ribonucléotides sont considérés comme étant les premières espèces à avoir émergé sur Terre. En milieu aqueux, leur formation est défavorable thermodynamiquement. Les voies de synthèse de nucléotides décrites en phase homogène impliquent l…, In the « RNA world» prebiotic scenario, ribonucleotide polymers are considered as the first biochemical species to have emerged. However, in aqueous solution, their formation through conventional mechanisms of condensation is thermodynamically forbidden. Several synthesis pathways of nucleotides…
