A European Science and Technology Roadmap for Graphene, Related Two-Dimensional Crystals, and Hybrid Systems hints at the opportunities to be harvested from, and the need for, the development of atomically precise manufacturing (APM).

The Theory Prize was given for research into diamond nanoparticles; the Experimental Prize was given for development of scanning tunneling microscope (STM) technology.
Positioning two or more molecules along a long DNA strand can cause the DNA molecule to adopt different shapes if the molecules interact. Quickly and cheaply separating these shapes by a simple gel electrophoresis assay provides a wealth of information about how the molecules interact.
Design and computational simulation of amyloid proteins of diverse functions from diverse sources enable the self-assembly of proteins that could provide scaffolds for diverse applications.
RNA origami brings new dimensions to nucleic acid nanotechnology by exploiting the much greater variety of RNA structural motifs (compared to DNA) to do what cannot easily be done with DNA origami, like fold into predetermined nanostructures rapidly while being transcribed.
Iterative coupling, purification, and cyclization of a large collection of organic building blocks promises a vast array of complex small and medium sized molecules as candidates for drug discovery, catalysis, and nanotechnology.
A commentary over at Gizmodo argues that ideas about molecular manufacturing that sounded like science fiction in 1986 now sound more like science fact.
The idea that nanorobots fabricated by atomically precise manufacturing processes are a likely part of our future, and that this is a good thing, is appearing more frequently, largely as a result of Drexler’s recent book Radical Abundance.
An overview of three decades of progress in DNA nanotechnology emphasizes bringing programmed motion to DNA nanostructures, including efforts to incorporate design principles from macroscopic mechanical engineering.
Scaffolded DNA origami is combined with hinges of single- or double-stranded DNA to built simple machines parts that have been combined to program simple to complex motions.
One example is presented of how well the meme is spreading that nanotechnology will evolve toward atomically precise manufacturing that will in turn bring forth a world of abundance.
Combinations of different types of DNA nanorobots, implementing different logic gates, work together to tag a specific type of cell in a living cockroach depending on the presence or absence of two protein signals.
A more general computational framework predicts the structures of 2D and 3D-curved DNA nanostructures impossible to predict using previously available computational methods. May lead to 3D-printing DNA nanostructures?
A new strategy to form bonds between carbon atoms opens the way to a wide variety of molecular architectures that had been difficult or impossible to access using previous methods.
Advances in the de novo design of coiled-coil proteins made by two different research groups proceeding by two different routes demonstrate that the range of protein nanostructures potentially available for various molecular machine systems is significantly larger than the range of such structures already exploited by natural selection.
A general framework is presented for using 32-nucleotide DNA bricks to build large two-dimensional crystals up to 80 nm thick and incorporating sophisticated three-dimensional features.
The US National Science Foundation announced a new grant program to develop and apply next-generation networking to advance nanotechnology and other emerging technologies to meet important national needs.
A small, interactive group of invited experts gathered in Palo Alto recently to discuss prospects for revolutionary advances in energy storage, transmission, and generation through nanotechnology.
The need for improved imaging and characterization on the nanoscale was emphasized in the 2007 Roadmap and again at the 2013 Foresight Conference on Atomic Precision. We noted last year a new advancement in atomic-scale resolution of 10-nm platinum particles, requiring multiple imaging techniques in combination, and recently the marked improvement in optical imaging for [...]
To emulate the process by which nature assembles complex organic molecules by passing subunits through a series of enzyme domains, UK chemists developed a procedure to elongate a boronic ester by using a reagent that inserts into carbon-boron bonds with precise control of molecular configuration.
