Monolayer protected gold clusters interface

Noble metal quantum clusters. Chemistry of gold-sulphur interface on monolayer protected clusters (MFCs) has long attracted research interest. These materials have a nanosized metal core containing hundreds or thousands of atoms with monolayers of surfactants/ligands on its surface. The metal core made of dense packing of metal atoms forming nanocrystals with specific lattice planes on its surface. 

Chapters 8 and 13 reviewed the application of SECM to the study of charge and electron transfer at the liquid-liquid and solid-liquid interfaces, respectively. Most studies have used molecular mediators (Chapter 1). However, there is a continued interest in nanoparticles, for example, of metals and semiconductors. These can also be studied by SECM. Eor example, SECM was used to determine the rate of electron transfer for gold monolayer-protected clusters (MPCs) as a function of the surface thiol group chain length. Such studies are more difficult than with molecular mediators because...
