A Graftable Quaternary Ammonium Biocidal Polymer Reduces Biofilm Formation and Ensures Biocompatibility of Medical Devices

Houssam Bouloussa, Azzam Saleh‐mghir, Claire Valotteau, Chahrazad Cherifi, Narjès Hafsia, Martine Cohen‐solal, Charles Court, Anne‐claude Crémieux, Vincent Humblot

A quaternized polyvinylpyridine (Q‐PVP) polymer methanolic solution synthesized in a single step is used to covalently graft titanium surfaces. Q‐PVP is quaternized with varying N+/N ratios. 1 cm2 pure titanium plates are polished and activated. Treated samples are grafted by spin coating or dip‐…

Maghemite nanoparticles and maghemite/silica nanocomposite microspheres as magnetic Fenton catalysts for the removal of water pollutants

Nassira Ferroudj, Jimmy Nzimoto, Anne Davidson, Delphine Talbot, Emmanuel Briot, Vincent Dupuis, Agnès Bée, Mohamed Salah Medjram, Sébastien Abramson

Maghemite nanoparticles (-Fe 2 O 3 NP) and maghemite/silica nanocomposite microspheres (-Fe 2 O 3 /SiO 2 MS) have been evaluated as magnetic heterogeneous Fenton catalysts. The catalysts were fully characterized by electronic microscopies, magnetometry, XRD, UV–vis–NIR spectroscopy, and sorption…

Lipase-embedded Silica Nanoparticles with Oil-filled Core-Shell Structure: Stable and Recyclable Platforms for Biocatalysts

Yasutaka Kuwahara, Takato Yamanishi, Takashi Kamegawa, Kohsuke Mori, Michel Che, Hiromi Yamashita

Lipase enzyme was embedded within silica nanoparticles with oil-filled core-shell structure. The enzyme embedded within such architecture retained all of its activity and showed high catalytic performance both in water and in organic media with optimal stability and recyclability.

Coordination chemistry approach for the end-to-end assembly of gold nanorods

P.R. Selvakannan, Eddy Dumas, Frédéric Dumur, Christine Péchoux, Patricia Beaunier, Arnaud Etcheberry, Francis Secheresse, Hynd Remita, Cédric Mayer

Gold nanorods synthesized by radiolysis were selectively end-functionalized by a fully conjugated thiol bearing a pendant terpyridine group; addition of ferrous ions led to the end-to-end 1D self-assembly of the nanorods. Similar results have been obtained when the preformed [(HStpy)Fe(tpySH)](2+)…

Using Prussian blue analogue nanoparticles confined into ordered mesoporous silica monoliths as precursors of oxides

Virgile Trannoy, Émilie Delahaye, Giulia Fornasieri, Patricia Beaunier, Anne Bleuzen

Powdered Prussian blue analogues (PBAs) and PBAs confined in ordered mesoporous silica monoliths were used as oxide precursors through thermal treatment under an oxidizing atmosphere. The study focuses on the transformation of the alkali cation-free CoCo PBA of chemical formula K0.1CoII4[CoIII(CN)6…
