Gold Nanorod Coating with Silica Shells Having Controlled Thickness and Oriented Porosity: Tailoring the Shells for Biosensing

Vincent Pellas, Juliette Blanchard, Clément Guibert, Jean-Marc Krafft, Antoine Miche, Michèle Salmain, Souhir Boujday

The coating of gold nanorods with a silica shell (AuNR@SiO2) is an effective way to extend their use in a wide variety of biomedical applications. A silica shell offers numerous advantages as it provides more stability, frees the surface from toxic cetyltrimethylammonium bromide (CTAB), and…

Selective uptake of La3+ ions with polyoxometalates-functionalized mesoporous SBA-15: An EXAFS study

Ourania Makrygenni, Faiza Lilia Bentaleb, Dalil Brouri, Anna Proust, Franck Launay, Richard Villanneau

In this work, mesoporous materials based on inorganic/organic polyoxometalate (POMs) hybrids with the ability of further incorporating heterometallic lanthanum cations were designed. On the basis of the La3+ coordination to vacant organophosphonyle derivatives of POMs previously studied, herein…

Silica-coated gold nanorods biofunctionalization for localized surface plasmon resonance (LSPR) biosensing

Vincent Pellas, Fadoua Sallem, Juliette Blanchard, Antoine Miche, Sara Martinez Concheso, Christophe Méthivier, Michèle Salmain, Souhir Boujday

We introduce here the engineering of nanobiosensors designed from gold nanorods coated with an ultrathin layer of silica (AuNR@SiO2) and biofunctionalized with antibodies for the Localized Surface Plasmon Resonance (LSPR) biosensing of proteins. Despite the outstanding properties of AuNRs, their…

UHV Deposition of the Gly-Pro Dipeptide on Cu(110) by Sublimation or Electrospray Ionization

Christophe Méthivier, Vincent Humblot, Claire-Marie Pradier

While most of the peptide adsorption studies, in vacuum, are achieved by sublimation, we demonstrate here the possible use of electrospray ionization (ESI) to deposit entire peptides, possibly surrounded by solvated ions, on a surface in ultra high vacuum (UHV) conditions. This paper is then…

Investigation of ion-selective electrodes with neutral ionophores and ionic sites by EIS. II. Application to K+ detection

Claude Gabrielli, Patrick Hemery, Pierre Letellier, Michele Masure, Hubert Perrot, Marie-Isabelle Rahmi, Mireille Turmine

The impedance of an ion-selective electrode (ISE) to potassium with valinomycin as the ionophore and KBΦ4 as the ionic sites was measured. The membrane was made of PVC with DNP as a plasticizer. The influence of the content of the plasticizer and the membrane thickness was investigated. The…

Influence of the preparation procedure on the nature and environment of vanadium in VSiBEA zeolite: XRD, DR UV-vis, NMR, EPR and TPR studies

Rafal Baran, Yannick Millot, Thomas Onfroy, Frédéric Averseng, Jean-Marc Krafft, Stanislaw Dzwigaj

Two series of VxSiBEA(I) and VxSiBEA(II) zeolites have been prepared by a two-steps postsynthesis method which consists, in the first step, in the dealumination of TEABEA zeolite by two different procedures to obtain SiBEA(I) and SiBEA(II) zeolites and then, in the second step, in contacting the…

Specificinteractions of functionalisedgoldsurfaces with ammonium perchlorate or starch; towards a chemical cartography of their mixture

D. Mercier, C. Mercader, S. Quere, Lionel Hairault, Christophe Methivier, Claire-Marie Pradier

By functionalising gold samples, planar wafers or AFM tips, with an acid- or an amino acid-terminated thiols, mercaptoundecanoic acid (MUA) and homocystein (H-Cyst) respectively, we were able to differentiate the interactions with ammonium perchlorate (AP) and starch (S), two components of a…

Elie Sayah, Camille La Fontaine, Valérie Briois, Dalil Brouri, Pascale Massiani

The evolution of supported silver species of a pre-calcined Ag/Al2O3 catalyst was monitored upon thermal treatment under an air flow enriched with 3000 ppm of ethanol (EtOH) using transmission electron microscopy and UV-visible and X-ray absorption spectroscopies. A special focus is put on the…
