Co, Fe and CoFe oxide nanoparticle assemblies within an ordered silica matrix: effects of the metal ions and synthesis pathway on the microstructure and magnetic properties

Laura Altenschmidt, Patricia Beaunier, Eric Rivière, Giulia Fornasieri, Amélie Bordage, Anne Bleuzen

The magnetic properties of nanoparticle assemblies strongly depend on the structural and morphological characteristics of the individual nanoparticles as well as on their organization within the assembly. Here, we present the synthesis of cobalt and/or iron oxide nanoparticles within the ordered…

Antibody-Gold Nanoparticle Bioconjugates for Biosensors: Synthesis, Characterization and Selected Applications

Lu Zhang, Yacine Mazouzi, Michèle Salmain, Bo Liedberg, Souhir Boujday

Antibody-Gold nanoparticle (Ab-AuNP) bioconjugates are widely used in the field of biosensing. This prompted researchers to set up various strategies to conjugate antibodies to gold nanoparticles. Optimal conjugation is of critical importance, as the Ab-AuNP bioconjugates should be stable while…

C3-Alkylation of furfural derivatives by continuous flow homogeneous catalysis

Grédy Kiala Kinkutu, Catherine Louis, Myriam Roy, Juliette Blanchard, Julie Oble

The C3-functionalization of furfural using homogeneous ruthenium catalysts requires the preinstallation of an ortho -directing imine group, as well as high temperatures, which did not allow scaling up, at least under batch conditions. In order to design a safer process, we set out to develop a…

Exploring the self-assembly of dumbbell-shaped polyoxometalate hybrids, from molecular building units to nanostructured soft materials

Mireia Segado Centellas, Madeleine Piot, Raphaël Salles, Anna Proust, Ludovic Tortech, Dalil Brouri, Sébastien Hupin, Benjamin Abécassis, David Landy, Carles Bo, Guillaume Izzet

The formation of hierarchical nanostructures using preformed dumbbell-like species made of covalent organic–inorganic polyoxometalate (POM)-based hybrids is herein described. In this system, the presence of charged subunits (POM, metal linkers, and counter ions) in the complex molecular…

Revisiting the Mukaiyama-type epoxidation for the conversion of styrene into styrene carbonate in the presence of O 2 and CO 2

Matthieu Balas, Asma Mayoufi, Richard Villanneau, Franck Launay

Since its first report in the early 1990s, Mukaiyama-type aerobic epoxidation involving the presence of an aldehyde as an electron donor is considered as an interesting oxidation reaction. Among the various metal catalysts efficient for this process, salen-type complexes have many advantages: i)…

Interactions of Calcium with Chlorogenic and Rosmarinic Acids: An Experimental and Theoretical Approach

Estelle Palierse, Cédric Przybylski, Dalil Brouri, Claude Jolivalt, Thibaud Coradin

Chlorogenic (CA) and rosmarinic (RA) acids are two natural bioactive hydroxycinnamic acids whose antioxidant properties can be modulated by the chelation of metal ions. In this work, the interactions of these two carboxylic phenols with calcium ions and the impact of such interactions on their…

Direct quantification of surface coverage of antibody in IgG-Gold nanoparticles conjugates

Lu Zhang, David Hu, Michèle Salmain, Bo Liedberg, Souhir Boujday

It is of paramount importance to be able to accurately quantify surface coverage of antibodies on gold nanoparticles (AuNP) so as to optimise the sensitivity of AuNP-based immunosensors. Herein, we developed a fluorescence-based method to directly quantify rabbit immunoglobulin G (IgG) used as…

Core–Shell Gold/Silver Nanoparticles for Localized Surface Plasmon Resonance-Based Naked-Eye Toxin Biosensing

Alexis Loiseau, Lu Zhang, David Hu, Michèle Salmain, Yacine Mazouzi, Raphaël Flack, Bo Liedberg, Souhir Boujday

The localized surface plasmon resonance (LSPR) phenomenon provides a versatile property for biodetection. Herein, this unique feature was employed to build a homogeneous optical biosensor to detect staphylococcal enterotoxin A (SEA) in solution down to very low levels by naked-eye readout. If the…
