Unmasking Photolithography: A Versatile Way to Site-Selectively Pattern Gold Substrates

摘要

Patterned substrates with well-defined micro- and nanoscale features are central to the development of a broad range of applications and fields, including, but not limited to, microelectronics, solar cell development, and biotechnology. Typically, these applications require the functionalization of inorganic substrates to meet the specific demands of an application. While this is classically achieved using photoresist, lift-off techniques, and chemical etching, one of the methods that has emerged for direct conjugation of active molecules to substrates is thiol-terrninated self-assembled monolayers (SAMs) on gold, silver, copper, palladium, and platinum substrates.
