With chemical modification, stable RNA nanoparticles go 3-D

For years, RNA has seemed an elusive tool in nanotechnology research - easily manipulated into a variety of structures, yet susceptible to quick destruction when confronted with a commonly found enzyme. By replacing a chemical group in the macromolecule, researchers have found a way to bypass RNase and create stable three-dimensional configurations of RNA, greatly expanding the possibilities for RNA in nanotechnology.

Colloidal quasi-crystals discovered

An international research group has discovered colloidal quasi-crystals for the first time. In contrast to the quasi-crystals previously documented, which can only be produced under special laboratory conditions, they are simply structured polymers that evolve through self-assembly. Due to their structural characteristics, they will probably be used in the development of innovative devices in photonics.

NIST advances single photon management for quantum computers

The quantum computers of tomorrow might use photons, or particles of light, to move around the data they need to make calculations, but photons are tricky to work with. Two new papers by researchers working at the National Institute of Standards and Technology (NIST) have brought science closer to creating reliable sources of photons for these long-heralded devices.

Real-world graphene devices may have a bumpy ride

Electronics researchers love graphene. But creating graphene-based devices will be challenging, say researchers at the National Institute of Standards and Technology (NIST), because new measurements show that layering graphene on a substrate transforms its bustling speedway into steep hills and valleys that make it harder for electrons to get around.

Secrets of mysterious metal hotspots uncovered by new single molecule imaging technique

The secrets behind the mysterious nano-sized electromagnetic 'hotspots' that appear on metal surfaces under a light are finally being revealed with the help of a BEAST. Researchers at the Berkeley Lab have developed a single molecule imaging technology, dubbed the Brownian Emitter Adsorption Super-resolution Technique (BEAST), that has made it possible for the first time to directly measure the electromagnetic field inside a hotspot.

Triblock spheres provide a simple path to complex structures

University of Illinois materials scientists have developed a simple, generalizable technique to fabricate complex structures that assemble themselves. The team demonstrated that they can produce a large, complex structure - an intricate lattice - from tiny colloidal particles called triblock Janus spheres.
