Arrays of pure semiconducting carbon nanotubes for nanoelectronics

A very efficient and scalable method of completely removing metallic carbon nanotubes from mixtures of metallic and semiconducting carbon nanotubes produces arrays suitable for many applications and for studies of thin film transistors.

Dynamic nanomachines for DNA nanotechnology inspired by proteins

Programmed assembly and disassembly of rigid 3D DNA origami objects has been achieved by designing complementary surface shapes based upon weak stacking interactions to create simple nanomachines.

Preserving protein function in DNA-protein nanostructures

Linking proteins to DNA scaffolds to produce complex functional nanostructures can require chemistry that damages protein function. A new systematic approach avoids exposing proteins to damaging conditions.

Single molecule pump concentrates small molecules

A rotaxane-based single molecule pump combines cycling oxidation-reduction potential of the solution with kinetic barriers to moving backward to concentrate small ring molecules against an energy gradient.

Conference video: Microscopic Reversibility: The Organizing Principle for Molecular Machines

At the 2013 Conference Dean Astumian contrasted macroscopic machines at static equilibrium and molecular machines at dynamic equilibrium, and presented information ratchets and microscopic reversibility as the organizing principle of molecular machines.

Conference video: Multi-Million Atom Simulations for Single Atom Transistor Structures

At the 2013 Conference Gerhard Klimeck presented the work of his computational nanotechnology network modeling nanoelectronic devices, using simulations of multi-million atom domains to understand the function of single atom devices embedded in larger nanostructures.

Nanoparticles shepherd DNA into cells to regulate immune response

DNA sequences designed to either stimulate a specific immune response or to down-regulate an undesirable response deliver superior performance when organized on nanoparticles to reach their intended cellular targets.

Nanowires and bacteria harnessed for artificial photosynthesis

A prototype system to produce chemicals and fuels from sequestered carbon dioxide, water, and sunlight uses semiconductor nanowires to produce electron-hole pairs, which are then used by two types of bacteria to produce oxygen and a variety of useful chemical products.

Science and technology roadmaps for nanotechnology

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).

Nanothreads formed from smallest possible diamonds

A new form of carbon produced by very slowly releasing benzene compressed at 200,000 times atmospheric pressure may be the strongest material possible.
