DNA origami

The best introduction to DNA nanotechnology

August 28, 2010

For a good overview of structural DNA nanotechnology and DNA origami (a molecular wonder of the modern world), see this presentation from a course in the College of Engineering at the University of Illinois. The subject calls for a strong visual presentation, and the slides deliver this together with a good description of DNA engineering [...]

A programmable nanoscale assembly line

May 20, 2010

When I picked up my copy of this week’s Chemical & Engineering News this evening, I found that the lead article begins with this:
Futuristic visions of nanobots that travel the body to treat disease and construct compounds one atom at a time got a little closer to reality this week, thanks to two advances in [...]

Carbon Nanotube Transistors through DNA Origami

November 12, 2009

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 [...]
