Electrochemical properties of gold nanoparticles assembly at polarised liquid|liquid interfaces

Hubert Girault, Mohamad Hojeij, Nathalie Younan, Lydie Ribeaucourt

Capacitance measurements of a polarised liquid|liquid interface show that the capacitance of the interface increases in the presence of an adsorbed monolayer of citrate-coated gold nanoparticles. This unusual observation can be explained by an increase of ...
