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.
Bulk nanoscale technologies were used to create three-segment nanowires of gold and nickel, and magnetic bearings of gold, nickel, and chromium. Combinations of DC and AC electric fields were used to assemble nanomotors that can spin at speeds up to 18,000r.p.m., and for up to 15 hours.
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.
IBM researchers engineered a class of molecules called block copolymers to self-assemble into dense patterns to extend the capabilities of photolithography.
Mixing two different types of cylindrical nanoparticles causes them to reorganize into smaller spherical nanoparticles. A mechanism to release drugs only inside cells that internalize both types?
Computational simulations demonstrate that pentagonal tiling to give a variant of graphene based on pentagons rather than on hexagons is dynamically, thermally, and mechanically stable.
Applications of nanotechnology to wearable electronics and other portable devices will benefit from the discovery that adding an insulating layer to a piezoelectric nanostructure increases the output voltage by up to 200 times.
A simple method of producing nanoporous alumina surface discourages bacteria from attaching and forming biofilms, with potential applications in medicine, dentistry, and food processing.
