A DNA clamp engineered for higher specificity and higher affinity may improve cancer diagnosis and treatment and may also mean better control over building nanomachines.
A possible forerunner to a future molecular assembly line uses an artificial DNA motor to transport an artificial nanoparticle along a carbon nanotube track.
A study of RNA structures actually present in cells reveals that cells spend energy restricting thermodynamically driven RNA folding so that fewer RNA structures are found in cells than in test tubes.
A recently released technology report titled Nano-solutions for the 21st century outlines nanotech-based solutions to global challenges. Several years in the making, the report was co-authored by Dennis Pamlin, Research Fellow at the Chinese Academy of Social Sciences Research Center for Sustainable Development (RCSD web site currently in Chinese only), and Eric Drexler, Academic Visitor [...]
Using DNA nanotechnology to control and organize molecular motors and the molecular tracks that they run on, a novel nanotrain transports molecular cargos tens of micrometers.
Eric Drexler’s TEDx talk entitled “A Future of Radical Abundance: Transforming the Material Basis of Civilization” is available for viewing on Youtube as well as on Drexler’s blog site. As described by the Oxford Martin School, where Drexler is a scholar with the Programme on the Impacts of Future Technology: Dr. Eric Drexler’s talk from [...]
A major advance in the computational design of proteins that bind tightly to specific small molecules will facilitate several technologies, possibly including the development of atomically precise manufacturing.
Graphene molecules a bit more than one nanometer across and greatly distorted from planarity have altered properties and offer novel building blocks for nanotechnology.
A limited set of videos from the January 2013 Foresight Conference have been made available. John Randall started the Conference presentations describing the patterned silicon Atomic Layer Epitaxy (ALE) approach to atomically precise manufacturing.
A porous metal-organic framework ‘host’ soaks up molecular ‘guests’ to form a crystalline complex, the structure of which can be determined by X-ray crystallography, providing atomic-resolution structures of minute amounts of guest molecules, and perhaps eventually other nanostructures.
A pillar constructed and positioned using DNA nanotechnology holds two gold nanoparticles and a dye molecule to enhance fluorescence over a hundred fold.
Two open access reviews portray the widening approach of DNA nanotechnology toward more complex atomically precise systems.
A simple DNA scaffold organizes light-collecting molecules for artificial photosynthesis.
Biotechnology-based isolation and amplification of sequence-verified clones of DNA oligonucleotides will provide longer and less expensive materials for building complex DNA nanostructures and nanomachinery.
Recently we pointed at a Forbe’s interview with Eric Drexler, in anticipation of his pending new book Radical Abundance. The book has shipped, and Drexler’s tour schedule now includes a few stops on the coasts of the U.S: New York: May 6th Los Angeles: May 8th & 9th Seattle: May 9th Find exact times and [...]
Nanotechnology researchers in London have used a scanning tunneling microscope to create atomically precise quantum states from dangling bonds on a silicon surface.
Revolution of DNA around a central channel, rather than rotation, is the method used by a viral molecular motor to package DNA. A structure facilitating bottom-up assembly may lead to roles in nanotechnology for these nanomotors.
In anticipation of Eric Drexler’s new book, Forbes contributor Bruce Dorminey interviews him about the meaning of nanotechnology and its revolutionary prospects. Selected excerpt: … In what fields would APM cause the most pronounced economic disruption and the collapse of global supply chains to more local chains? The digital revolution had far-reaching effects on information [...]
By forcing the geometry of the junctions upon which DNA nanotechnology depends, researchers have increased the collection of 2D and 3D structures that they can build to include wire frames and mesh structures.
