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

Electroless Deposition of Metal Nanoislands on Aminothiolate-Functionalized Au(111) Electrodes
TL;DR: In this paper, selective electroless deposition (ELD) can be used as a tool for electrochemical nanostructuring, and a first step was taken to bound palladium ions to an aminothiolate (AT) layer on an Au(111)...

Physical mechanisms governing pattern fidelity in microscale offset printing
TL;DR: In this article, a combination of experiments and equilibrium simulations was used to identify the physical mechanisms controlling ink transfer and pattern fidelity in offset printing of liquid polymers curable by exposure to ultraviolet light onto flat and unpatterned silicon and glass substrates.

Imaging the irradiance distribution in the optical near field
TL;DR: In this article, the use of a sensitive photoresist for direct imaging of optical intensity profiles in near-field photolithographic experiments is described, which provides a reliable semiquantitative image of the irradiance distribution in the near field; experiment and theory correlate adequately.

The use of self-assembled monolayers and a selective etch to generate patterned gold features
TL;DR: Using a number of techniques, such as micromachining, microwriting, electron-beam lithography, ion-beam, and ion beam, it is possible to form patterns of SAMs on the Au surface.
