Polarizable QM/Classical Approaches for the Modeling of Solvation Effects on UV–Vis and Fluorescence Spectra: An Integrated Strategy

Daniele Loco, Natalia Gelfand, Sandro Jurinovich, Stefano Protti, Alberto Mezzetti, Benedetta Mennucci

Hybrid methods combining quantum chemistry and classical models are largely used to describe solvent effects in absorption and emission processes of solvated chromophores. Here we compare three different formulations of these hybrid approaches, using a continuum, an atomistic, or a mixed…

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…

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…

Investigating the Mukaiyama-type epoxidation reaction of alkenes with Cr(III) salophen catalysts: A confrontation between experiments and DFT calculations

Arnaud Marvilliers, Jean-Baptiste Harlé, Franck Launay, Sébastien Blanchard, Anne Gauvin-Bialecki, Hélène Gérard, Richard Villanneau

This study aimed at the complete elucidation of the mechanism of the Mukaiyama-type alkene epoxidation reaction using the [(salophen)CrIIICl] precatalyst, by combining spectroscopic (UV–visible and EPR) studies, catalytic reactivity and quantum chemical modeling. These studies performed in parallel…

Dual Thermo- and pH-Responsive N -Cyanomethylacrylamide-Based Nano-Objects Prepared by RAFT-Mediated Aqueous Polymerization-Induced Self-Assembly

Nicolas Audureau, Fanny Coumes, Jean-Michel Guigner, Clément Guibert, François Stoffelbach, Jutta Rieger

We report the straightforward synthesis of dual stimuli-responsive nano-objects using a RAFT-mediated polymerization-induced self-assembly (PISA) process in water. The key to complex and tunable responsiveness was the copolymerization of N-cyanomethylacrylamide, providing UCST-type polymers, with a…

Engineering of Antimicrobial Surfaces by Using Temporin Analogs to Tune the Biocidal/antiadhesive Effect

Pierre-Carl Oger, Christophe Piesse, Ali Ladram, Vincent Humblot

Proliferation of resistant bacteria on biomaterials is a major problem leading to nosocomial infections. Due to their broad-spectrum activity and their ability to disrupt bacterial membranes through a rapid membranolytic mechanism, antimicrobial peptides (AMPs) are less susceptible to the…

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,…

Enhancing the magnetic anisotropy of maghemite nanoparticles via the surface coordination of molecular complexes

Yoann Prado, Niéli Daffé, Aude Michel, Thomas Georgelin, Nader Yaacoub, Jean-Marc Greneche, Fadi Choueikani, Edwige Otero, Philippe Ohresser, Marie-Anne Arrio, C. Cartier Dit Moulin, Ph. Sainctavit, Benoit Fleury, Vincent Dupuis, Laurent Lisnard, Jérôme Fresnais

Superparamagnetic nanoparticles are promising objects for data storage or medical applications. In the smallest—and more attractive—systems, the properties are governed by the magnetic anisotropy. Here we report a molecule-based synthetic strategy to enhance this anisotropy in sub-10-nm…
