Nanometer-scale gold particles are currently intensively investigated for possible applications in catalysis, sensing, photonics, biolabeling, drug carriers and molecular electronics Nanometer-scale gold particles are currently intensively investigated for possible applications in catalysis, sensing, photonics, biolabeling, drug carriers and molecular electronics. The particles are prepared in a solution from gold salts and their reactive gold cores can be stabilized with various organic...

Researchers at the Department of Chemistry and Nanoscience Center (NSC) of the University of Jyväskylä (Dr Olga Lopez-Acevedo and Professor Hannu Häkkinen) have resolved the structural, electronic and optical properties of a chiral gold nanocluster that remained a mystery for ten years. The theoretical structure was confirmed via comparison to experimental results obtained by X-ray diffraction from powder samples of the pure cluster material. The theoretical work was done in...
