Catalysis by Supported Gold Nanoclusters
The physical and chemical properties of supported Au clusters are markedly sensitive to cluster size and morphology. To investigate the origin of the unique properties of nanosized Au clusters, model catalysts consisting of Au clusters of varying sizes have been prepared on single crystal TiO2(110) and ultrathin films of single crystalline TiO2, SiO2, and Al2O3. The morphology, electronic struc...
متن کاملRedox properties of self-assembled gold nanoclusters.
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 MPCs and the substrate electrode on the absolute standard redox potential of MPCs was theoretically considered and studied experimentally.
متن کاملControlling gold nanoclusters by diphospine ligands.
We report the synthesis and structure determination of a new Au22 nanocluster coordinated by six bidentate diphosphine ligands: 1,8-bis(diphenylphosphino) octane (L(8) for short). Single crystal X-ray crystallography and electrospray ionization mass spectrometry show that the cluster assembly is neutral and can be formulated as Au22(L(8))6. The Au22 core consists of two Au11 units clipped toget...
متن کاملCytotoxicity of nucleus-targeting fluorescent gold nanoclusters.
Gold nanoclusters (AuNCs) with ultra small sizes and unique fluorescence properties have shown promising potential for imaging the nuclei of living cells. However, little is known regarding the potential cytotoxicity of AuNCs after they enter the cell nucleus. The aim of this study is to investigate whether and how nucleus-targeting AuNCs affect the normal functioning of cells. Highly stable, w...
متن کاملStructural properties: magic nanoclusters of gold.
nature nanotechnology | VOL 2 | MAY 2007 | www.nature.com/naturenanotechnology 273 MSNs and the green fl uorescent protein (GFP) marker encoded in the DNA was expressed in the cells and detected by microscopy. Delivery is effi cient because the minimum amount of DNA required to detect marker expression was 1,000-fold lower than that required when using conventional methods to deliver DNA into p...
