Is it Worth Starting Now? Surely, you will say, it would have been wonderful if back in 1959 people had taken Feynman seriously and really tried the Feynman path: we’d have the full-fledged paraphernalia of real, live molecular machinery now, with everything ranging from nanofactories to cell-repair machines. After all, it’s been 50 years. The… Continue reading Feynman's Path to Nanotech (part 5)
Two recent publications provide more evidence of the growing capability of DNA scaffolds to support complex and interactive functions.
DNA origami structures act as seeds to program the construction of structures up to 100 times larger.
Two independently controlled nanomechanical devices can be positioned on a two-dimensional DNA grid so that they can cooperate to capture between them one of four DNA building blocks, determined by which of two possible states each device is set to.
A group of German scientists have developed a new slant on DNA nanotechnology by using atomic force microscopy to assemble a DNA scaffold on a surface to which molecular building blocks can then bind.
Snowbird, Utah is the place to be for nanotechnologists on April 22-25 for the 5th Annual Conference on Foundations of Nanoscience (FNANO08): Self-Assembled Architectures and Devices. Those of you who have attended Foresight research conferences will recognize a number of familiar names and lots of new ones. Mark Sims of Nanorex tells us that they… Continue reading Do-it-yourself nanotechnology objects from DNA
Researchers at IBM are developing DNA nanotechnology to assemble nanoelectronic components into arrays in a bid to replace current lithographic methods of making computer chips.
Tetrahedrons made from DNA that extend and shorten in response to added short strands of DNA may provide new nanotech methods of drug delivery, but may present even more exciting possibilities for atomically precise functional nanosystems.
Forbes announces its top five nanotechnology breakthroughs for 2006, and we’re not surprised to see the winner of this year’s Foresight Institute Feynman Prize in Nanotechnology listed as #1: 1. DNA origami, at Caltech 2. Nanomagnets to clean up drinking water, at Rice 3. Arrays connect nanowire transistors with neurons, at Harvard 4. Single nanotube… Continue reading Forbes' 2006 Top 5 nanotechnology breakthroughs
