Introduction to Magnetic Nanoclusters

Spontaneous formation of dipolar metal nanoclusters.

The adsorption of three- and four-atom Ag and Pd clusters on the alpha-Al(2)O(3) (0001) surface is explored with density functional theory. Within each adsorbed cluster, two different cluster-surface interactions are present. We find that clusters simultaneously form both ionic bonds with surface oxygen and intermetallic bonds with surface aluminum. The simultaneous formation of disparate elect...

Thermodynamic stability of ligand-protected metal nanoclusters

Despite the great advances in synthesis and structural determination of atomically precise, thiolate-protected metal nanoclusters, our understanding of the driving forces for their colloidal stabilization is very limited. Currently there is a lack of models able to describe the thermodynamic stability of these 'magic-number' colloidal nanoclusters as a function of their atomic-level structural ...

Functionalization of metal nanoclusters for biomedical applications.

Metal nanoclusters (NCs) are emerging as a new class of functional nanomaterials in the area of biological sensing, labelling, imaging and therapy due to their unique physical and chemical properties, such as ultrasmall size, HOMO-LUMO transition, strong luminescence together with good photostability and biocompatibility. A recent surge of interest in this field is the surface functionalization...
