A DNA-replication machinein action
In his comment on Molecular Machine Assembly: The Movie, Drew Whitehouse reminded me of a set of excellent animations of biological productive nanosystems, work done by Drew Berry. These videos are based on scientific data describing molecular structure and function, and from what I’ve seen, Drew Berry’s work is the best of [...]Everyone knows how to assemble things: Just grasp the parts and put them together. Self-assembly, though, doesn’t work at all like this, and as a consequence, it presents major challenges. Despite its inherent difficulties and limitations, self-assembly is the leading means for implementing atomically precise nanotechnologies today, and I expect it will lead for years to come. Self-assembly is a powerful method, and powerful enough to provide a path to nanotechnologies that are yet more powerful. Improving methods for making complex structures by self-assembly is an enormously important area of research.

We will build the roads and bridges, the electric grids and digital lines that feed our commerce and bind us together. We will restore science to its rightful place, and wield technology's wonders to raise health care's quality and lower its cost. We will harness the sun and the winds and the soil to fuel our cars and run our factories.”Why mention this on a nanotechnology blog? Simple, really; every one of the areas mentioned above will be enabled by nanoscale technologies.

As every mechanical engineer knows, the stiffness of a material — its elastic modulus — is often a critical property; likewise in nanomechanical engineering, though in part for a different reason. I’d like to say a few words about this, then discuss some materials of interest in implementing nanosystems. And there is something [...]"Nanotechnology is the engineering of functional systems at the molecular scale. In its advanced form, which should be achieved within the next decade or two, the technology will allow a revolution in manufacturing—building powerful products with atomic precision from the bottom up—and could fundamentally alter our ability to confront challenging issues such as climate change. Some experts confidently predict that once exponential general-purpose molecular manufacturing is achieved, our worries about global warming and climate change will be over. A relatively simple solution like tiny balloons fitted with adjustable mirrors could, they say, give us all the control we will need to moderate warming and create preferred climate conditions."

As such, the assembly and synthesis of these nanostructures, which demonstrate multiple dimensionality, using a bottom-up approach would be useful. In this example, 1D ZnO nanowires about 80nm in diameter grow vertically out of the junctions of 80nm thick ZnO nanowalls.
