• , nanowires of a number of different metals have been synthesized, including Pt, Pb, Ni, Co, and Fe. Platinum is a noble metal with interesting nanowire applications in sensorics and catalysis. Recently, the synthesis of Pt nanowires at 65 °C from an alkaline platinum bath (Platinum-OH, Metakem) in a two

• negative potentials, only the more noble metal is deposited, while at more negative potential, both metals are deposited. By keeping the concentration of the more noble metal in the electrolyte much lower than the concentration of the less noble metal, the less noble metal is mainly deposited containing a

• attractive for use in biomedicine since it is a noble metal, does not oxidize readily and has low to no toxic effects [6]. This also makes it suitable for use as a solid lubricant, and studies in liquids on the nanoscale to determine friction reduction and wear protection have not been reported. Spherical Au

The catalytic activity of highly dispersed gold particles either supported on metal oxides or embedded in metal oxides as discovered by Haruta et al. [5] served as pioneering work in the field of noble-metal catalysis in general

Microcontact printing can be used to transfer a monolayer of thiols onto a noble metal substrate as described in [36][37]. A similar procedure to that described in [37] was used here to
