Charge transport through redox active [H₇P₈W₄₈O₁₈₄]^33- polyoxometalates self-assembled onto gold surfaces and gold nanodots

K. Dalla Francesca, Stéphane Lenfant, M. Laurans, F. Volatron, G. Izzet, Vincent Humblot, C. Methivier, David Guérin, A. Proust, Dominique Vuillaume

Polyoxometalates (POMs) are redox-active molecular oxides, which attract growing interest for their integration into nano-devices, such as high-density data storage non-volatile memories. In this work, we investigated the electrostatic deposition of the negatively charged [H7P8W48O184]33− POM onto…

Design of TiO2/Au nanoparticle films with controlled crack formation and different architectures using a centrifugal strategy

Abdelhafed Taleb, Frederic Mesguich, Thomas Onfroy, Xue Yanpeng

Here we present an approach to design hybrid nanocomposite films based on TiO2/Au nanoparticles using centrifugation processes. The prepared nanocomposite films have been characterized by different techniques such as FEGSEM, TEM, BET and XRD. Furthermore it is demonstrated that centrifugal force…

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…

In Situ Solid–Gas Reactivity of Nanoscaled Metal Borides from Molten Salt Synthesis

Guillaume Gouget, Damien P. Debecker, Ara Kim, Giorgia Olivieri, Jean-Jacques Gallet, Fabrice Bournel, Cyril Thomas, Ovidiu Ersen, Simona Moldovan, Clément Sanchez, Sophie Carenco, David Portehault

Metal borides have mostly been studied as bulk materials. The nanoscale provides new opportunities to investigate the properties of these materials, e.g., nanoscale hardening and surface reactivity. Metal borides are often considered stable solids because of their covalent character, but little is…
