Cu-modified hydroxy-apatite as catalyst for Glaser–Hay CC homo- coupling reaction of terminal alkynes

Birgit Maaten, Jamal Moussa, Christophe Desmarets, Patrick Gredin, Patricia Beaunier, Tõnis Kanger, Kaia Tõnsuaadu, Didier Villemin, Michel Gruselle

The oxidative Glaser–Hay coupling reaction of terminal alkynes is a very important reaction in organic chemistry to achieve the synthesis of diyne compounds. In general the reaction is performed under homogeneous conditions using Cu(I) or Cu(II) salts in the presence of a reagent such as…

Quantifying Cell Traction Forces at the Individual Fiber Scale in 3D: A Novel Approach Based on Deformable Photopolymerized Fiber Arrays

Pierre Ucla, Joanne Le Chesnais, Henri Ver Hulst, Xingming Ju, Isabel Calvente, Ludovic Leconte, Jean Salamero, Isabelle Bonnet, Catherine Monnot, Hélène Moreau, Jessem Landoulsi, Vincent Semetey, Sylvie Coscoy

The forces exerted by cells upon the fibers of the extracellular matrix play a decisive role in cell motility in development and disease. How the local physical properties of the matrix (such as density, stiffness, orientation) affect cellular forces remains poorly understood. Existing approaches…

Naked Eye Immunosensing of Food Biotoxins Using Gold Nanoparticle-Antibody Bioconjugates

Lu Zhang, Michèle Salmain, Bo Liedberg, Souhir Boujday

Colorimetric immunoassays using gold nanoparticles (AuNP) form a special class of assays where AuNP act as a transducer to monitor binding events between an antigen and an antibody. Indeed, AuNP display unique optical properties that can been exploited in various ways to develop biosensors. One of…

Immobilization of polyoxometalate hybrid catalysts onto mesoporous silica supports using phenylene diisothiocyanate as a cross-linking agent

Ourania Makrygenni, Dalil Brouri, Anna Proust, Franck Launay, Richard Villanneau

The hybrid derivative of heteropolytungstate bearing two aniline groups, namely (nBu4N)3[NaHPW9O34{As(O)C6H4NH2}2], was post-functionalized in the presence of 1,4-phenylene diisothiocyanate (PDITC). The resulting molecular moiety was characterized by IR, 1H and 31P NMR spectroscopy. In a second…

Binding mechanism of oligopeptides on solid surface: assessing the significance of single-molecule approach

Joanne Lê-Chesnais, Marie Steffenhagen, Christophe Méthivier, Dominique Costa, Daniela Rodriguez, Jean-François Lambert, Emmanuel Maisonhaute, Jessem Landoulsi

This paper addresses the complementarity and potential disparities between single-molecule and ensemble-average approaches to probe the binding mechanism of oligopeptides on inorganic solids. Specifically, we explore the peptide/gold interface owing to its significance in various topics and its…

Fluorescent core-shell nanoparticles and nanocapsules using comb-like macromolecular RAFT agents: synthesis and functionalization thereof

Chloé Grazon, Jutta Rieger, Patricia Beaunier, Rachel Méallet-Renault, Gilles Clavier

Fluorescent nanoparticles and nanocapsules (FNPs) were synthesized via a one-pot RAFT miniemulsion process copolymerizing BODIPY-methacrylate and styrene in water. Ultra-bright sub-100 nm core–shell nanoparticles could be obtained with BODIPY covalently linked in the core, and possessing various…
