Properties, fabrication and applications of plasmonic semiconductor nanocrystals

Haibo Yin, Yasutaka Kuwahara, Kohsuke Mori, Catherine Louis, Hiromi Yamashita

We highlight three widely explored oxide-based plasmonic materials, including H x MoO 3−y , H x WO 3−y , and Mo x W 1−x O 3−y , and their applications in catalysis.

Detection of hydrogen peroxide using dioxazaborocanes: elucidation of the sensing mechanism at the molecular level by NMR and XPS measurements

Thomas Caron, Pascal Palmas, Céline Frénois, Christophe Méthivier, Eric Pasquinet, Claire-Marie Pradier, Françoise Serein-Spirau, Lionel Hairault, Pierre Montméat

A fluorescent dioxazaborocane was synthesised and characterized, in order to study its turn-off sensing process for hydrogen peroxide detection. The exposure of the dioxazaborocane to diluted vapours of H2O2 led to a strong non reversible quenching of the fluorescence. Both NMR and XPS analyses…

Redox-Triggered Control of Cell Adhesion and Deadhesion on Poly(lysine)- g -poly(ethylene oxide) Adlayers

Louise Hespel, Julien Dupré de Baubigny, Pierre Lalanne, Simon de Beco, Mathieu Coppey, Catherine Villard, Vincent Humblot, Emmanuelle Marie, Christophe Tribet

Spontaneous adsorption of poly(lysine)-g-poly(ethyleneglycol) comb-like copolymers (PLL-g-PEG) is a versatile mean to coat substrates with polymer layers that resist cell adhesion. We prepared redox cleavable PLL-g-PEG to switch adhesion on demand. Redox sensitivity was obtained by introducing…

Synthesis of RNA nucleotides in plausible prebiotic conditions from ab initio computer simulations

Andrea Pérez-Villa, Antonino Marco Saitta, Thomas Georgelin, Jean-François Lambert, François Guyot, Marie-Christine Maurel, Fabio Pietrucci

Understanding the mechanism of spontaneous formation of ribonucleotides under realistic prebiotic conditions is a key open issue of origins-of-life research. In cells, de novo and salvage nucleotide enzymatic synthesis combines 5-phospho-α-d-ribose-1-diphosphate (α-PRPP) and nucleobases.…
