Andrew Maynard – Optimism and Concerns with Nanotechnology
Andrew Maynard, Chief Science Advisor to the Project on Emerging Nanotechnologies at the Woodrow Wilson International Center for Scholars discusses a few reasons for optimism and concerns with nanotechnology. This interview was taken at the Science Museum of Virginia during NanoDays 2008. Read more: Andrew Maynard – 2020science.org NISE Net – www.nisenet.org

CNSE Professor of Nanoengineering John Hartley speaks about the capabilities of CNSE’s electron beam technology, which can achieve resolutions at the very limit of imaging technology.
Dr. Hildy: Nanotechnology for Environmental Remediation
January 25, 2012 — One Cell One Light™ Radio with Dr. Hildegarde Staninger™, RIET-1 onecellonelightradio.wordpress.com Guests: DR. ZHONG LIN (ZL) WANG nanoscience.gatech.edu and MICHAEL EDWARD blueplague.org Throughout history, new technology has brought a sense of wonderment and fear to those unfamiliar with it. In post-Civil War America, the steam-powered engine brought the possibility of speedier travel, but also the fear of cultural pollution brought about by this ease of movement. Currently, technology changes so rapidly that it often goes unnoticed — incremental improvements to products we already own don’t alert the deep-rooted fear of the unknown that we all share. But with a the practical application of a once-theoretical nanotechnology rapidly becoming reality, those fears are once more rearing their ugly head. But, are they warranted? This week on One Cell One Light Radio, Dr. Staninger welcomes back to the program Dr. Zhong Lin (ZL) Wang, head of a leading group in nanoscience and nanotechnology at the Georgia Institute of Technology; and Michael Edward, who continues to be involved in the research into the health and toxicity problems following the 2010 Gulf of Mexico oil disaster, to discuss the practical applications of nanotechnology remediation and cleanup of toxic substances in the environment. After the April 2010 explosion of the Deepwater Horizon oil drilling platform, nearly five million gallons of crude oil flowed unabated into the waters of the …

NEW DNA ROBOTS
For the first time, microscopic robots made from DNA molecules can walk, follow instructions and work together to assemble simple products on an atomic-scale assembly line, mimicking the machinery of living cells, two independent research teams announced Wednesday. These experimental devices, described in the journal Nature, are advances in DNA nanotechnology, in which bioengineers are using the molecules of the genetic code as nuts, bolts, girders and other building materials, on a scale measured in billionths of a meter. The effort, which combines synthetic chemistry, enzymology, structural nanotechnology and computer science, takes advantage of the unique physical properties of DNA molecules to assemble shapes according to predictable chemical rules. Until now, such experiments had yielded molecular novelties, from smiley faces so small that a billion can fit in a teaspoon to molecule-size boxes with lids that can be opened, closed and locked with a DNA key. These new construction projects bring researchers a step closer to a time when, at least in theory, scientists might be able to build test-tube factories that churn out self-assembling computers, rare chemical compounds or autonomous medical robots able to cruise the human bloodstream. In one of the projects, a pioneering research group based at New York University built the prototype of a molecular factory in which mobile DNA robots assembled gold particles in eight different ways, in response to chemical commands …
Disruptive Innovation: Nanotechnology and the Future of Computing
(June 23, 2011) We are used to permanent improvements in the price performance of consumer electronics and the like. But soon a new nanoelectronic switch technology will be required to sustain this progress. John Kelly discusses how nanotechnology will drive the next wave of disruptive innovation and the potential implications for business and society.
