The US National Science Foundation announced a new grant program to develop and apply next-generation networking to advance nanotechnology and other emerging technologies to meet important national needs.
A small, interactive group of invited experts gathered in Palo Alto recently to discuss prospects for revolutionary advances in energy storage, transmission, and generation through nanotechnology.
The need for improved imaging and characterization on the nanoscale was emphasized in the 2007 Roadmap and again at the 2013 Foresight Conference on Atomic Precision. We noted last year a new advancement in atomic-scale resolution of 10-nm platinum particles, requiring multiple imaging techniques in combination, and recently the marked improvement in optical imaging for [...]
To emulate the process by which nature assembles complex organic molecules by passing subunits through a series of enzyme domains, UK chemists developed a procedure to elongate a boronic ester by using a reagent that inserts into carbon-boron bonds with precise control of molecular configuration.
The US NSF has announced a program to support fundamental research leading to complex nanosystems.
A new DARPA program seeks to bridge the gap from atoms to macroscale product manufacture in two steps, the first of which is from atoms to micrometer-scale feedstocks. DNA origami may be part of the solution.
A 10-fold larger breadboard and 350-fold lower DNA synthesis costs make DNA origami a more useful stepping-stone toward atomically precise manufacturing.
Swiss researchers have used biomolecular shuttles to capture molecular building blocks from solution and transport them across fluid flow boundaries to be further manipulated in a subsequent chamber.
Register by Sept. 5 to attend a Proposers Day webinar on either Sept. 9 or 11 to learn the technical objectives of DARPA’s new “Atoms to product: Aiming to make nanoscale benefits life-sized” program.
An interview with UK nanotechnologist Richard Jones argues that the surest and most efficient path to advanced nanomachine function will incorporate or mimic biomolecular nanomachinery rather than scaled down rigid conventional machinery.
Attaching a 200-nm-diameter magnetic bead to a 1-nm diameter synthetic molecular machine allowed optical visualization of the motion of the machine and manipulation with a magnetic tweezers.
Rice University’s breakthrough nanoporous silicon oxide technology for resistive random-access memory (RRAM) appears poised for commercialization.
Study shows more than 500 firms involved in nanobiotechnology, which is expected to soon triple in size. Research points to the importance of broad networks and deep collaborations.
With biotech fundamental to several paths to advanced nanotechnology, a way to do biotech experiments in the cloud offers small groups the chance to quickly test their ideas.
B.R.AI.N.S., Berkeley BioLabs, and Foresight Institute to build an open source biological parts repository and design and distribute a line of “How-to Build Biological Machines” educational kits.
Enveloped DNA nanostructures were developed to escape attacks from nucleases and the immune system, opening a path to ever more sophisticated DNA nanomedical devices.
The complex molecular recognition code of RNA offers RNA nanotechnology a greater variety of 3D structures and functions than are present in DNA nanotechnology, but the RNA structures can be fragile. New RNA triangles that resist boiling solve this problem.
A swinging DNA arm added to a DNA scaffold makes it possible for two enzymes attached to the scaffold to complete a coupled chemical reaction.
A bacterium has been engineered to stably propagate a DNA written with six letters instead of the usual four, greatly expanding the number of amino acids, both natural and synthetic, that can be genetically encoded. Further work could lead to novel proteins incorporating these additional amino acids, and from there to novel materials, devices, and machines.
