Création de surfaces antibiofilms par greffage covalent de peptides et enzymes antibactériens sur les surfaces de cuivre et de titane, Creation of antibiofilm surfaces : covalent grafting of antimicrobial peptides and enzymes onto copper and titanium surfaces

Jessie Peyre

La contamination bactérienne et le développement de biofilms marins sont des problèmes récurrents, et terriblement coûteux sur les structures immergées des bâtiments de l'armée. L'emploi de composés bactéricides et nocifs pour l'écosystème est désormais interdit. Les travaux menés…, Bacterial contamination and formation of biofilms on immersed structures in seawater are frequent and at the origin of high cost maintenance treatments. The use of compounds biocidal, but also harmful for the ecosystem, is nowadays forbidden. The aim of this thesis work was to find new preventive…

Degradation of organic pollutants by a new eco-compatible process : kinetic approache using FTIR-ATR spectroscopy at the oxide-water interface, Dégradation des polluants organiques par un nouveau procédé éco-compatible : approche cinétique utilisant la spectroscopie FTIR-ATR à l'interface oxyde-eau

Ana Carolina Schuh Frantz

This work addresses the issue of soil and water decontamination by exploring environmentally friendly decontamination strategies that involve the degradation of organic contaminants, particularly antibiotics. Building on the work of Ardo et al. (2015), this study examines the degradation of…, Ce travail aborde la problématique de la dépollution des sols et des eaux en explorant des stratégies de dépollution respectueuses de l'environnement mettant en jeu la dégradation de contaminants organiques, notamment les antibiotiques. En s'appuyant sur les travaux d'Ardo et al. (…

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…

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…

Core–Shell Gold/Silver Nanoparticles for Localized Surface Plasmon Resonance-Based Naked-Eye Toxin Biosensing

Alexis Loiseau, Lu Zhang, David Hu, Michèle Salmain, Yacine Mazouzi, Raphaël Flack, Bo Liedberg, Souhir Boujday

The localized surface plasmon resonance (LSPR) phenomenon provides a versatile property for biodetection. Herein, this unique feature was employed to build a homogeneous optical biosensor to detect staphylococcal enterotoxin A (SEA) in solution down to very low levels by naked-eye readout. If the…

How does CO capture process on microporous NaY zeolites? A FTIR and DFT combined study

Olivier Cairon, Hazar Guesmi

Reliable experimental IR and theoretical approaches, both investigating CO adsorption on NaY faujasites, are supporting that CO capture occurs through the completion of the vacant coordination of Na+ cations located in the accessible SII sites. As a result, carbonyl adsorbed species are formed by…
