Antibody-Gold Nanoparticle Bioconjugates for Biosensors: Synthesis, Characterization and Selected Applications

Lu Zhang, Yacine Mazouzi, Michèle Salmain, Bo Liedberg, Souhir Boujday

Antibody-Gold nanoparticle (Ab-AuNP) bioconjugates are widely used in the field of biosensing. This prompted researchers to set up various strategies to conjugate antibodies to gold nanoparticles. Optimal conjugation is of critical importance, as the Ab-AuNP bioconjugates should be stable while…

Heterogeneous Fenton-like reactions in natural soils and sediments at neutral pH with O2 as oxidant

Elora Bourbon, Frederic Averseng, Thierry Allard, Pierre Le Pape, Sylvie Nélieu, Xavier Carrier, Guillaume Morin, Elodie Guigon, Fulvia Baratelli, Sophie Ayrault

Heterogeneous Fenton-like processes using O2 as oxidant and iron(II) minerals as substrate is a rapidly growing research field with important implications especially for in-situ organic pollutant degradation in natural media. These reactions can be conducted at neutral pH and several minerals are…

A new glance at ruthenium sorption mechanism on hydroxy, carbonate, and fluor apatites: Analytical and structural studies

K. Tõnsuaadu, M. Gruselle, F. Villain, R. Thouvenot, M. Peld, V. Mikli, R. Traksmaa, Patrick Gredin, Xavier Carrier, L. Salles

The sorption mechanism of Ru3+ ions on hydroxy (HAp), carbonate (CO3HAp), and fluor apatites (FAp) has been studied in detail. Ru apatites were obtained by reaction of the apatites with RuCl3 in aqueous solution. The structure and composition of the ruthenium-modified apatites were studied by…

Surface segregation in AuPd alloys: Ab initio analysis of the driving forces

Jérôme Creuze, Hazar Guesmi, Christine Mottet, Beien Zhu, Bernard Legrand

In order to determine the energetic driving forces for surface segregation in AuPd alloys, we use a combined approach coupling ab initio calculations and an analysis via an effective Ising model. Previously, this approach has been used successfully in the framework of N-body interatomic potentials…

Time-of-Flight Secondary Ion Mass Spectrometry Investigation of the Orientation of Adsorbed Antibodies on SAMs Correlated to Biorecognition Tests

Victor Lebec, Souhir Boujday, Claude Poleunis, Claire-Marie Pradier, Arnaud Delcorte

The adsorption of an antiglutamate dehydrogenase (Anti-GDH) antibody on different surfaces was studied to probe its orientation and bioactivity. Three different situations were investigated: physisorption on a −COOH-terminated thiols self-assembled monolayer (SAM) on gold, covalent grafting on the…
