Gold clusters and gold nanoparticles have been shown to have very interesting and promising electronic, optical and catalytic properties.1–3 These properties are very useful for several applications in diverse fields as for instance in biomedicine (e.g. sensing and labelling), nanoelectronics, photonics, sensing and catalysis.1–4 Whereas the term cluster describes a particle with a well-defined number of atoms which usually is smaller than 3 nm in size, the term nanoparticle covers all particle sizes, but a particle larger than 1 nm in size up to 100 nm is meant. The number of atoms plays no crucial role for the nanoparticle, but instead the nanoparticle shape, for example visualised by a Wulff construction which determines the crystal shape in the thermodynamic equilibrium. The crystal shape is constructed in such a way that the free energy of the surface is minimised by having a constant volume.
