From Alan Boyle, science editor at MSNBC, news of DNA self-assembly work at the lab of Eric Winfree of Caltech: “A computer scientist has developed a method to weave stringy DNA molecules into nanometer-scale, two-dimensional patterns ranging from smiley faces to a map of the Americas. “Experts say the ‘DNA origami’ procedure laid out by… Continue reading DNA origami from Caltech may be useful for nanoscale factory
Liveblogging the Foresight Conference: Apologies for not blogging yesterday’s afternoon session, including the “Controversies in Nanotechnology” talk (by me), the IP talk by Stanford prof Mark Lemley, the IP panel (I was moderating), and the Public Equity panel — featuring the colorful Michael Weiner of Biophan, who advised against taking investment funds from VCs. This… Continue reading Rigid addressable nanoscaffolds & single-stranded DNA origami
Roland Piquepaille writes "Scientists at The Scripps Research Institute (TSRI) have constructed a single strand of DNA that spontaneously folds into a highly rigid, nanoscale octahedron. These clonable structures represent a breakthrough because they can be manipulated with the standard tools of molecular biology and can easily be cloned, replicated, amplified, evolved, and adapted for various applications. This opens the way to future nanotools and to the minuscule computers of tomorrow, even if we are quite far from any real products. This overview contains more details. You'll also see a great picture of a clonable DNA octahedron, roughly the size of a small virus."

Presenter Erik Benson, researcher at Oxford University Working on building small structures and machines from DNA. Summary: Erik Benson, researcher at Oxford University, presented a brief overview of DNA origami mechanisms. His primary project is the construction of a simple 2D printer built out of DNA origami. Three structures – rails, a print head, and… Continue reading Erik Benson, researcher at Oxford University | Nanoscale Machinery from DNA
Presenters William Shih, Harvard University William is overseeing an effort to apply Synthetic Biology approaches to the development of self-assembling DNA nanostructures and devices for use in biomedical applications. To achieve structures of even greater complexity, his laboratory is pioneering methods for hierarchical assembly of these particles into three-dimensional networks with site-specific control over chemical… Continue reading Molecular Detection via DNA Nanotech & Neural Nets | William Shih, Harvard & Lulu Qian, Caltech
Ultrafast molecular machines made using DNA nanotechnology have now been demonstrated. Over the past several years molecular machines made using DNA nanotechnology, especially the scaffolded DNA origami technology, have grown more complex and more functional (see, for example, here, here, here, and here). Long-time Foresight member Dr. Robert P. Meagley writes to point out that… Continue reading Ultrafast DNA robotic arm: A step toward a nanofactory?
