Using DNA nanotechnology to cast arbitrarily shaped nanoparticles

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.

Light-driven molecular flapping emits white light

A phosphorescent molecule is made to flap like a butterfly when absorbed light shortens the distance between two platinum atoms.

A Breakthrough in 3D Imaging by EM Alone

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… Continue reading A Breakthrough in 3D Imaging by EM Alone

Tailoring the shapes of organic molecules by assembly-line synthesis

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.

Scaffolded DNA origami improvements advance DNA nanotechnology

A 10-fold larger breadboard and 350-fold lower DNA synthesis costs make DNA origami a more useful stepping-stone toward atomically precise manufacturing.

Novel multifunctional nanoparticle for diagnosis and therapy

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.

Proof of principle for nanoscale assembly line

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.

Seeing and touching a single synthetic molecular machine

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.

Tunable Assembly of Nanoparticles for (Photovoltaic) Devices

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… Continue reading Tunable Assembly of Nanoparticles for (Photovoltaic) Devices

Nanotechnology-based next generation memory nears mass production

Rice University’s breakthrough nanoporous silicon oxide technology for resistive random-access memory (RRAM) appears poised for commercialization.
