Tuning the shape and size of hybrid gold nanoparticles by porphyrins using seed-mediated synthesis

Jolanda Spadavecchia, Sandra Casale, Jessem Landoulsi, Claire-Marie Pradier

We report the synthesis of hybrid gold nanostructures by means of seed/growth approach, using porphyrin molecules (protoporphyrin IX) in addition to cetyltetraammonium bromide (CTAB) as surfactants and/or shape-modulating agents. The combination of CTAB and porphyrin yields stable complexes that…

Surface plasmon resonance biosensors incorporating gold nanoparticles.

Erin Bedford, Jolanda Spadavecchia, Claire-Marie Pradier, Frank Gu

SPR biosensing is increasingly popular for the detection of a multitude of biomolecules. It offers label-free detection and study of proteins, nucleic acids, and other biomolecules in real time. A recent trend involves incorporation of AuNPs, either within the sensing surface itself or as signal…

Plasmonic photothermal destruction of uropathogenic E. coli with reduced graphene oxide and core/shell nanocomposites of gold nanorods/reduced graphene oxide

Kostiantyn Turcheniuk, Charles-Henri Hage, Jolanda Spadavecchia, Aritz Yanguas Serrano, Iban Larroulet, Amaia Pesquera, Amaia Zurutuza, Mariano Gonzalez Pisfil, Laurent Heliot, Julie Bouckaert, Rabah Boukherroub, Sabine Szunerits

The development of non-antibiotic based treatments against bacterial infections by Gram-negative uropathogenic E. coli is a complex task. New strategies to treat such infections are thus urgently needed. This report illustrates the development of pegylated reduced graphene oxide nanoparticles (rGO-…

Bioconjugated gold nanorods to enhance the sensitivity of FT-SPR-based biosensors

Jolanda Spadavecchia, Sandra Casale, Souhir Boujday, Claire-Marie Pradier

n this paper, we report a feasible solvent-free approach for the synthesis and self-assembling of gold nanorods after bioconjugation to antibodies; scanning electron microscopy (SEM) and transmission electron microscopy (TEM) images revealed a remarkable shape and size narrow distribution, as well…

Interactions of Calcium with Chlorogenic and Rosmarinic Acids: An Experimental and Theoretical Approach

Estelle Palierse, Cédric Przybylski, Dalil Brouri, Claude Jolivalt, Thibaud Coradin

Chlorogenic (CA) and rosmarinic (RA) acids are two natural bioactive hydroxycinnamic acids whose antioxidant properties can be modulated by the chelation of metal ions. In this work, the interactions of these two carboxylic phenols with calcium ions and the impact of such interactions on their…

Effect of water on cobalt speciation during solid-state synthesis of Co2+/ZSM5 catalysts: quantitative study by TPR and XAS

Eric Marceau, Michel Che, Françoise Villain, Younès Ben Taarit

The effect of water on cobalt speciation in the synthesis of Co2+/ZSM5 catalysts is quantitatively studied by the combined use of macroscopic and local characterization techniques, TPR and X-ray absorption spectroscopies, respectively. The addition of a small quantity of water to cobalt acetate and…

On the clarification of the IR stretching vibration assignment of adsorbed N2 on Rh0 and Rhd+ surface atoms of supported Rh crystallites

Céline Fontaine-Gautrelet, Jean-Marc Krafft, Gérald Djéga-Mariadassou, Cyril Thomas

The low temperature adsorption of N2 on Rh/SiO2 samples of various particle-size distributions was followed by FTIR. The addition of O2 pulses on Rh0 surfaces saturated with chemisorbed N2 allowed us to reassign stretching frequencies attributed originally to N2-Rh0 to N2-RhΔ+. The formation of the…

Catalytic activity of HAlBEA and NixHAlBEA zeolites in hydrogen-assisted dehydrochlorination of 1,2-dichloroethane into vinyl chloride monomer

Rafal Baran, Anna Srebowata, I.I. Kaminska, D. Łomot, Stanislaw Dzwigaj

HAlBEA zeolite is prepared by calcination of parent TEABEA zeolite at 823 K for 3 h in air following ionic exchange with NH4NO3 solution. NixHAlBEA zeolites are prepared by impregnation of HAlBEA with an aqueous solution of Ni(NO3)2, following a drying at 333 K to obtain NixHAlBEA. The calcination…
