Heavy-ion irradiation of interstellar carbonaceous and siliceous composite dust analogs. Cosmic ray-grain interactions at the nanometer scale

Eddy Abdo, Emmanuel Dartois, Marin Chabot, Olivier Sublemontier, Thibault Nguyen Trung, Emeline Charon, Frieder Koch, Pascal Simon, Ina Schubert, Marie Godard, Thomas Pino, Cécile Engrand, David Troadec, Sandra Casale, Joffrey Fréreux

Context. Interstellar dust made of siliceous and carbonaceous grains is exposed to cosmic ray ions in the diffuse and dense medium. This highly energetic interaction not only affects the morphology of such systems, but also plays a role in altering the surface and bulk chemistry. These two effects…

Fine-tuning protocols for accurate study of nanoparticle adhesion and uptake after foliar deposition

Mickael Wagner, Ilan Minerva, Aude Calas, Fadoua Sallem, Françoise Maubé, Camille Larue, Astrid Avellan

<div><p>Understanding interactions between plant leaves and nanoparticles (NPs) is crucial for advancing both and environmental and the safety of plant protection products. Recent studies showed how the fate of NPs on leaf surfaces is influenced by NP properties, plant surface, and…

Temporin-SHa peptides grafted on gold surfaces display antibacterial activity

Andres Lombana, Zahid Raja, Sandra Casale, Claire-Marie Pradier, Thierry Foulon, Ali Ladram, Vincent Humblot

Development of resistant bacteria onto biomaterials is a major problem leading to nosocomial infections. Antimicrobial peptides are good candidates for the generation of antimicrobial surfaces because of their broad-spectrum activity and their original mechanism of action (i.e. rapid lysis of the…

Probing the Orientation of β-Lactoglobulin on Gold Surfaces Modified by Alkyl Thiol Self-Assembled Monolayers

Victor Lebec, Jessem Landoulsi, Souhir Boujday, C. Poleunis, Claire-Marie Pradier, A. Delcorte

The adsorption of a globular protein on chemically well controlled surfaces was investigated in order to correlate its orientation to the surface properties. To this end, three different alkyl thiols, differing by their end group (−COOH, −CH3, and −NH2), were used to build up self-assembled…

Immobilisation of protein A on SAM's for the elaboration of immunosensors

Elisabeth Briand, Michèle Salmain, Chantal Compere, Claire-Marie Pradier

Binary mixtures of 11-mercaptoundecanoic acid (MUA) and other thiols of various lengths and terminal functions were chemisorbed on gold-coated surfaces via S-Au bonds to form mixed self-assembled monolayers (SAMs). Several values of the mole fraction of MUA in the thiol mixtures were tested and the…

Self-Regulating VO2 Photonic Pigments

Maria Letizia de Marco, Olivier Smith, Fanny Thorimbert, Cédric Boissière, Lionel Nicole, Jean-Marc Krafft, Clement Sanchez, Marco Faustini

Nanostructured photonic pigments exhibiting structural colors hold promises to replace conventional pigments for several applications. One emerging challenge in the field consists in integrating additional functionalities to the pigments beyond colors. For instance, integrating phase changing…

Self-Organization and/or Nanocrystallinity of Co Nanocrystals Effects on the Oxidation Process Using High-Energy Electron Beam

Ana Cazacu, Claudio Larosa, Patricia Beaunier, Guillaume Laurent, Paolo Nanni, Liliana Mitoseriu, Isabelle Lisiecki

We report the enhanced stability of Co nanocrystals (NCs) when they are highly ordered at both nanometer and micrometer scales. We show for the first time that both the crystalline structure of Co nanoparticles (NPs) and their 2D hexagonal organization have a significant impact on the oxidation…

Site-specific grafting on titanium surfaces with hybrid temporin antibacterial peptides

Nicolas Masurier, Jean-Baptiste Tissot, Douae Boukhriss, Said Jebors, Coline Pinese, Pascal Verdié, Muriel Amblard, Ahmad Mehdi, Jean Martinez, Vincent Humblot, Gilles Subra

Relying on a membrane-disturbing mechanism of action and not on any intracellular target, antimicrobial peptides (AMP) are attractive compounds to be grafted on the surface of implantable materials such as silicone catheters or titanium surgical implants. AMP sequences often display numerous…
