As I noted in a recent post on self-assembled nanoelectronics (“Carbon Nanotube Transistors through DNA Origami”), carbon nanotubes (CNTs) hold promise for self-assembled nanomechanical systems, too: They are orders of magnitude stiffer than biomolecules, and can serve not only as rigid components, but also as low-friction linear and rotary bearings to support moving parts.
Recent [...]

Caltech researchers have applied DNA-based self-assembly to bind pairs of carbon nanotubes into structures that can act as field-effect transistors. Nature Nanotechnology has a prepublication release of their paper, “Self-assembly of carbon nanotubes into two-dimensional geometries using DNA origami templates”; the work emerged from a collaboration centered on the Winfree lab. Physorg.com reports the story [...]
