Metal or other inorganic nanoparticles of 20 to 30-nm scale can be cast in arbitrary 3D shapes and configurations dictated by stiff, atomically precise molds constructed using scaffold DNA origami.
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 phosphorescent molecule is made to flap like a butterfly when absorbed light shortens the distance between two platinum atoms.
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.
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.
A nanoparticle that self-assembles from porphyrin, cholic acid, amino acids, and polyethylene glycol is a promising vehicle for delivering both imaging agents and cancer drugs to tumors.
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.
Nanotech promises more commonplace access to advanced technology as material and fabrication costs fall and traditional barriers to innovation are removed. Examples are already being seen globally: more access to laptops and cell phones in developing countries, desktop 3D printers, a surge in establishment of shared-use research facilities, etc. A couple recent cases getting attention [...]
Photovoltaics are an interesting case where atomic precision is not necessary to achieve potentially dramatic global impacts. Even an “ok efficiency” device that is easy to manufacture with reduced environmental hazard could have significant beneficial effects on energy resources and on device fabrication processes (which could, in turn, contribute to developments toward APM). The struggle [...]
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.
