Structural DNA nanotechnology arrays devices to capture molecular building blocks

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.

Cut-and-paste single molecule nanotechnology using DNA

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.

Do-it-yourself nanotechnology objects from DNA

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

Building chips with DNA nanotechnology

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.

DNA building blocks that change shape provide new tool for nanotechnology

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' 2006 Top 5 nanotechnology breakthroughs

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

More building blocks for DNA nanotechnology

Scientists Brew Tree-Shaped DNA: "Researchers from Cornell University have synthesized a new type of DNA that can be used as a nanotechnology building block. … The Cornell researchers have found a way to make branched, or Y-shaped DNA, and have constructed dendrimer, or tree-shaped, DNA by connecting branched DNA."
