TLDR
In this paper, Binnig and Rohrer used the scanning tunnelling microscope (STM) to position individual xenon atoms on a single-crystal nickel surface with atomic pre-cision.Abstract:
SINCE its invention in the early 1980s by Binnig and Rohrer1,2, the scanning tunnelling microscope (STM) has provided images of surfaces and adsorbed atoms and molecules with unprecedented resolution The STM has also been used to modify surfaces, for example by locally pinning molecules to a surface3 and by transfer of an atom from the STM tip to the surface4 Here we report the use of the STM at low temperatures (4 K) to position individual xenon atoms on a single-crystal nickel surface with atomic pre-cision This capacity has allowed us to fabricate rudimentary structures of our own design, atom by atom The processes we describe are in principle applicable to molecules also In view of the device-like characteristics reported for single atoms on surfaces5,6, the possibilities for perhaps the ultimate in device miniaturization are evidentread more

Self-directed growth of molecular nanostructures on silicon
TL;DR: An approach for fabricating nanoscale organic structures on silicon surfaces, employing minimal intervention by the tip of a scanning tunnelling microscope and a spontaneous self-directed chemical growth process, which should allow parallel fabrication of identical complex functional structures.

Technologies for nanofluidic systems: top-down vs. bottom-up - a review
TL;DR: It is concluded that technology in the region of 1-10 nm is lacking and potentially can be covered by using the pulsed-laser deposition method as a controlled way for thin film deposition (thickness of a few nanometers) and further structuring by the top-down method.

TL;DR: Scanning tunneling microscopy experiments show that such a spin-polarized state is essentially localized on the carbon sublattice opposite to the one where the hydrogen atom is chemisorbed, drives the direct coupling between the magnetic moments at unusually long distances.

Molecular manipulation using a tunnelling microscope
TL;DR: The accomplishment of the smallest yet, purposeful, spatially localized changes in matter, effected on a graphite surface is reported, believing that the changes result from the pinning of individual organic molecules to the graphite.
