• 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

• been a principal area of research in optical sensing devices [1][2][3][4]. 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
