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

Inverse design in search of materials with target functionalities
TL;DR: In this article, a new style of collaboration between theory and experiment is discussed, whereby the desired functionality of the new material is declared first and theoretical calculations are then used to predict which stable and synthesizable compounds exhibit the required functionality.

Machining oxide thin-films with an atomic force microscope: pattern and object formation on the nanometer scale
Charles M. Lieber,Yun Kim +1 more
TL;DR: An atomic force microscope has been used to machine complex patterns and to form free structural objects in thin layers of MoO3 grown on the surface of MoS2, suggesting application to nanometer-scale diffraction gratings, high-resolution lithography masks, and possibly the assembly of nanostructures with novel properties.

Life as a nanoscale phenomenon.
TL;DR: The living cell is considered as an integrated self-regulating complex chemical system run principally by nanoscale miniaturization, and it is proposed that this specific level of dimensional constraint is critical for the emergence and sustainability of cellular life in its minimal form.

TL;DR: It is shown that the supramolecular assembly of Fe and 1,4-benzenedicarboxylic acid molecules on a Cu surface results in ordered arrays of high-spin mononuclear Fe centres on a 1.5 nm square grid, opening a way to control the magnetic anisotropy in supramolescular layers akin to that used in metallic thin films.

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.
