Heteropolytungstate-decorated core-shell magnetic nanoparticles: A covalent strategy for polyoxometalate-based hybrid nanomaterials

Ourania Makrygenni, Emilie Secret, Aude Michel, Dalil Brouri, Vincent Dupuis, Anna Proust, Jean-Michel Siaugue, Richard Villanneau

Amino-functionalized core-shell magnetic nanoparticles have been covalently grafted with Polyoxometalates (POMs). These multifunctional nanocomposites have been obtained through the coupling of heteropolytungstate-based hybrids bearing carboxylic acid functions with aminopropyl functions that…

Room-Temperature Synthesis of Iron-Doped Anatase TiO2 for Lithium-Ion Batteries and Photocatalysis

Christian Andriamiadamanana, C. Laberty-Robert, Moulay Tahar Sougrati, Sandra Casale, Carine Davoisne, Snehangshu Patra, Frédéric Sauvage

Iron-doped nanocrystalline particles of anatase TiO2 have been successfully synthesized using a complete room-temperature synthetic approach, leading to particles of high surface area (280 m2/g) and a narrowed band gap of 2.3 eV. These particles were introduced for photocatalysis under white light…

A New Antibacterial N -Halamine Coating Based on Polydopamine

Nadia Nazi, Vincent Humblot, Catherine Debiemme

To prevent the formation of biofilms on material surfaces, the latter must have antibacterial properties. The aim of this study is to investigate the synthesis and the antibacterial effect of a new N-halamine coating based on polydopamine (PDA). The benefits of this coating are multiple, notably…

Cyto- and bio-compatibility assessment of plasma-treated polyvinylidene fluoride scaffolds for cardiac tissue engineering

Maria Kitsara, Gaëlle Revet, Jean-Sébastien Vartanian-Grimaldi, Alexandre Simon, Mathilde Minguy, Antoine Miche, Vincent Humblot, Thierry Dufour, Onnik Agbulut

As part of applications dealing with cardiovascular tissue engineering, drop-cast polyvinylidene fluoride (PVDF) scaffolds have been treated by cold plasma to enhance their adherence to cardiac cells. The scaffolds were treated in a dielectric barrier device where cold plasma was generated in a…
