Assembly and reactivity of nanoparticles at liquid / liquid interfaces

Bin Su

The interface between two immiscible electrolyte solutions (ITIES), or liquid|liquid interface, provides a defect-free junction for fundamental studies of adsorption phenomena, heterogeneous charge transfer reactions, and phase-formation processes. Recent ...

2-Dimensional Porphyrin Self-Assemblies at Molecular Interfaces

Hubert Girault, Nicolas Eugster, Bin Su

The heterodimer formed by electrostatic association of zinc(II) meso-tetrakis(N-methylpyridyl)porphyrin (ZnTMPyP) and zinc(II) meso-tetrakis(p-sulfonatophenyl)porphyrin (ZnTPPS) exhibits a strong affinity for the interface between water and 1,2-dichloroeth ...

Antioxidant Redox Sensors Based on DNA Modified Carbon Screen-Printed Electrodes

Hubert Girault, Bin Su

Antioxidant redox sensors based on DNA modified carbon screen-printed electrodes were developed. The carbon ink was doped with TiO2 nanoparticles, onto which double- strand DNA was adsorbed. A redox mediator, namely, tris- 2,2′-bipyridine ruthenium(II) [Ru ...

CdSe Sensitized Thin Aqueous Films: Probing the Potential Distribution Inside Multilayer Assemblies

Hubert Girault, Nicolas Eugster, Bin Su, Mohamad Hojeij

Ultrathin polypeptide multilayer films are assembled by the sequential electrostatic adsorption of monolayers of poly-L-lysine and poly-L-glutamic acid onto carboxylic acid terminated alkanethiol-modified gold surfaces. The polypeptide multilayer films are ...

Solvent Effect on Redox Properties of Hexanethiolate Monolayer-Protected Gold Nanoclusters

Hubert Girault, Bin Su

The capacitance of monolayer-protected gold nanoclusters (MPCs), CMPC, in solution has been theoretically reconsidered from an electrostatic viewpoint, in which an MPC is considered as an isolated charged sphere within two dielectric layers, the intrinsic ...

Reactivity of Monolayer-Protected Gold Nanoclusters at Dye-Sensitized Liquid/Liquid Interfaces

Hubert Girault, Nicolas Eugster, Bin Su

Hexanethiolate monolayer-protected gold nanoclusters (MPCs) were used as redox quenchers at the polarizable water/1,2-dichloroethane (DCE) interface. Photocurrent responses originating from the heterogeneous quenching of photoexcited water soluble porphyri ...

Simulations of the adsorption of ionic species at polarisable liquid liquid interfaces

Hubert Girault, Nicolas Eugster, Bin Su

The adsorption of ions at the interface between two immiscible electrolyte solutions (ITIES) is primarily controlled by the potential distribution across the interface, which in turn is influenced by the adsorption process. In the present paper, we simulat ...

Absolute Standard Redox Potential of Monolayer-Protected Gold Nanoclusters

Hubert Girault, Bin Su

The redox properties of monolayer-protected gold nanoclusters (MPCs) are considered from both the theoretical and experimental viewpoints. The “absolute standard redox potential” ([ ]abs) of MPCs is first derived from electrostatic considerations. A linear ...

Adsorption and photoreactivity of CdSe nanoparticles at liquid|liquid interfaces

Hubert Girault, Jean-Pierre Abid, Nicolas Eugster, Bin Su

The voltage induced assembly and photoreactivity of cadmium selenide (CdSe) nanoparticles protected by mercaptosuccinic acid are studied at the polarisable interface between water and 1,2-dichloroethane electrolyte solutions. Cyclic voltammograms and admit ...

Redox Properties of Self-Assembled Gold Nanoclusters

Hubert Girault, Bin Su

The redox properties of a monolayer of alkanethiolate-protected gold nanoclusters (MPCs) constructed on a gold slide electrode was studied in 1,2-dichloroethane (DCE) electrolyte solutions. The influence of the electrostatic interaction between attached MP ...
