TLDR
In this paper, a technique for patterning a self-assembled monolayer (SAM) on a gold substrate using an elastomer stamp was described, followed by selective etching in an aqueous, basic solution of cyanide ion and dissolved dioxygen (1M KOH, 0.1 M KCN).Abstract:
This letter describes a technique that can be used to produce well‐defined features of gold. The technique involves patterning of a self‐assembled monolayer (SAM) on a gold substrate using an elastomer stamp (fabricated either from a phenol‐formaldehyde polymer or polydimethylsiloxane), followed by selective etching in an aqueous, basic solution of cyanide ion and dissolved dioxygen (1M KOH, 0.1 M KCN). Electrically conductive structures of gold with dimensions as small as 1 μm have been produced using this procedure. Once a rubber stamp is fabricated, patterning and etching of gold substrates is straightforward. This method is convenient, does not require routine access to clean rooms and photolithographic equipment, and can be used to produce multiple copies of a pattern.read more

Oxygen’s Role in Aqueous Gold Cluster Synthesis
TL;DR: In this article, the role of radicals in the synthesis of water-soluble thiolate-protected gold nanoclusters is investigated, and it is shown that radicals, either from O2 or from radical initiators such as 4-hydroxy-TEMPO, are necessary components for synthesis.
