We have occasionally cited research in which DNA walkers move molecular components along DNA tracks. A very different approach to DNA motors has succeeded in moving micron-sized glass spheres sporting hundreds of DNA legs at 1000 times the speed of other DNA motors. …
Speaking of nanomedicine, nanoparticles, microRNAs, and cancer, another research group, this time at the Broad Institute of MIT and Harvard, has demonstrated the therapeutic potential of using the right nanoconjugate to deliver the right microRNAs to tumors. …
Nanotechnology will increasingly contribute to medicine through the development of increasingly complex, computer-controlled nanorobots (such as these early DNA origami-based prototypes we cited here and here). But even very simple devices exploiting nanoparticle-based molecular interactions are looking very promising. …
The powerful and elegant molecular recognition code that makes possible double helical DNA has also made scaffolded DNA origami and its parent field, structural DNA nanotechnology, probably the most widespread and useful approach to bottom-up molecular nanotechnology. The 2-nm diameter of the DNA helix leads to the suspicion, however, that the ultimate precision obtainable with these technologies might not be much better than 5 nm, more than an order of magnitude less precise than atomic precision. A paper published two months ago, however, demonstrates much finer control using a DNA hinge with “adjuster helices” to control the angle of the hinge. …
Recently we noted the accomplishments of James Tour, winner of the 2008 Foresight Institute Feynman Prize in the Experimental category, and his collaborators implementing a nanomaterial incorporating single-atom catalysts. Their most recent accomplishment is a single-molecule nanosubmarine. …
James Tour, winner of the 2008 Foresight Institute Feynman Prize in the Experimental category, and his collaborators continue to bring forward a variety of promising applications based upon graphene and other nanostructured materials. Recently we cited a nanotechnology computer memory breakthrough and before that a flexible supercapacitor from stacked nanomaterial. …

About the Foresight Institute
Foreseeing Future Technologies
Advancements in technologies such as nanotech, robotics, artificial intelligence, and biotech are promising to make major differences in our lives in the not-too-distant future, as the Industrial Revolution did to the agrarian world — to do for the physical world what the computer and Internet have done to the world of information.
Since 1986, the Foresight Institute has been in the forefront of a worldwide community of visionaries who work to help shape these possibilities into a positive, beneficial reality.
If you would like to help us understand the potential of these technologies, and influence their direction, please consider becoming a member of the Foresight community. With your support, Foresight will continue to educate the general public on these technologies and what they will mean to our society.
The Foresight Institute is a non-profit, member-supported 501(c)(3) organization. We offer membership levels appropriate to meet the needs and interests of individuals and companies. Donations are tax deductible.
Donate stock that’s appreciated in value. This is a win-win move. Donate stock and you won’t have to pay capital gains taxes on the profits, and the full value of the stock can be deducted as a charitable donation.
