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

Ultrathin functional star PEG coatings for DNA microarrays.
TL;DR: The direct spotting without additional activation and blocking steps of the surface demonstrates the potential of star PEG coatings as ultrathin surface modification for microarrays.

Crystal forming devices and systems and methods for using the same
TL;DR: In this article, a platen face with one or more fluid ports spatially correspond to a surface of a microfluidic device is described. And the platen actuator is used to push the platon against a micro-fluid device so that at least one of the fluid ports of the Platen is urged against one of its wells to form a pressure chamber.

Pinhole‐free large‐grained atomically smooth Au(111) substrates prepared by flame‐annealed template stripping
TL;DR: In this paper, a thin layer of gold on silicon is flame-annealed in air and then stripped from the template, and the resulting gold substrate surface is atomically smooth with most grains being larger than 1 μm 2.

Laser-assisted decomposition of alkylsiloxane monolayers at ambient conditions: rapid patterning below the diffraction limit
TL;DR: In this paper, a focused laser beam at a wavelength of 514 nm was used for patterning octadecylsiloxane monolayers at ambient conditions, which allowed for a well-confined local decomposition of the monolayer.

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.
