Catalytic Probe Lithography: Catalyst-Functionalized Scanning Probes as Nanopens for Nanofabrication on Self-Assembled Monolayers

Catalytic probe lithography: catalyst-functionalized scanning probes as nanopens for nanofabrication on self-assembled monolayers.

This article describes the use of scanning catalytic probe lithography for nanofabrication of patterns on self-assembled monolayers (SAMs) of reactive adsorbates. Catalytic writing was carried out by scanning over bis(omega-tert-butyldimethyl-siloxyundecyl)disulfide SAMs using 2-mercapto-5-benzimidazole sulfonic acid-functionalized gold-coated AFM tips. The acidic tips induced local hydrolysis ...

Scanning probe lithography of self-assembled monolayers

Systematic studies on scanning probe lithography (SPL) methodologies have been performed using self-assembled monolayers (SAMs) on Au as examples. The key to achieving high spatial precision is to keep the tip-surface interactions strong and local. Approaches include three atomic force microscopy (AFM) based methods, nanoshaving, nanografting, and nanopen reader and writer (NPRW), which rely on...

-functionalized self-assembled monolayers chemisorbed on ultraflat Au(111) surfaces for biological scanning probe microscopy in aqueous buffers

Two immobilization procedures for ultimately carrying out scanning probe microscopy of native biological macromolecules in buffer solution are presented. They are based on the preparation of ultraflat template-stripped gold surfaces and subsequent chemisorption of bioreactive -functionalized self-assembled monolayers. Immobilization was achieved either via amide bond formation or diazo linkage....

Nanofabrication by scanning probe microscope lithography: A review

In addition to its well-known capabilities in imaging and spectroscopy, scanning probe microscopy sSPMd has recently shown great potentials for patterning of material structures in nanoscales. It has drawn the attention of not only the scientific community, but also the industry. This article examines various applications of SPM in modification, deposition, removal, and manipulation of material...
