Optimized immobilization of gold nanoparticles on planar surfaces through alkyldithiols and their use to build 3D biosensors

Anne-Laure Morel, Rose-Marie Volmant, Christophe Methivier, Jean-Marc Krafft, Souhir Boujday, Claire-Marie Pradier

This paper describes a controlled way to immobilize gold nanoparticles on planar gold surfaces and the use of the resulting 3D platform to build up a 3D biosensor. The surface was first functionalized by grafting hexanedithiol, this molecule has 2 thiol end groups, which enables its chemical…

kinetics of the plasmon optical response of Au nanoparticles/TiO2 catalyst under O2 and H2 followed by differential diffuse reflectance spectroscopy

Yves Borensztein, Laurent Delannoy, Ruben G. Barrera, Catherine Louis

The changes in the optical properties of Au/TiO2 powder catalyst, prepared by the deposition-precipitation method, are measured in the visible range by use of a home-made diffuse differential reflectance spectrometer, when the ambient atmosphere is switched between H2 and O2. Two main features are…

Influence of the state of iron on CO oxidation on FeSiBEA zeolite catalysts

Izabela Hnat, Ireneusz Kocemba, Jacek Rynkowski, Thomas Onfroy, Stanislaw Dzwigaj

The influence of the state of iron on the catalytic properties of FexSiBEA zeolite in the oxidation of CO was investigated. Various FexSiBEA zeolites (x = 0.6, 1.0, 4.0 and 10 wt%) were prepared by a two-step post synthesis method. The presence of Fe(III) in tetrahedral coordination for low Fe…

Nanoscale antiadhesion properties of sophorolipid-coated surfaces against pathogenic bacteria

Claire Valotteau, Niki Baccile, Vincent Humblot, Sophie Roelants, Wim Soetaert, Christian V Stevens, Yves Dufrêne

A current challenge in nanomedicine is to develop innovative strategies to fight infections caused by multiresistant bacterial pathogens. A striking example is antiadhesion therapy, which represents an attractive alternative to antibiotics to prevent and treat biofilm-associated infections on…

Surface orientation dependent interaction of cobalt (II) precursors with alpha-alumina

Céline Chizallet, Christian Schlaup, Emiliano Fonda, Xavier Carrier

The performances of alumina-supported cobalt catalysts strongly depend on Co/alumina interactions, that are poorly understood. In the present work, α-alumina surfaces are used as models of polycrystalline support, to unravel their orientation dependent behavior by GI-EXAFS. The CoII/α-alumina…

Compared activity and stability of three Ni-silica catalysts for methane bi- and dry reforming

Karam Jabbour, M.N. Kaydouh, N El Hassan, H El Zakhem, Sandra Casale, Anne Davidson, Pascale Massiani

A low weight % of Ni (5 wt %) and the two solvents technique of deposition are used to obtain well-dispersed Ni-species (either particles or species dispersed on the silica surface) and avoid the formation of large particles on three silicas SBA-15, Aerosil 300 and diatoms MN3. Stability tests at…
