Tiny probes shine brightly to reveal the location of targeted tissues
Nanostructures called BRIGHTs seek out biomarkers on cells and then beam brightly to reveal their locations. In the tiny gap between the gold skin and the gold core of the nanoparticle, there is an electromagnetic hot spot that lights up the reporter molecules trapped there. BRIGHTs, which shine about 1.7 x 10^11 more brightly than isolated Raman reporters, are intended for use in noinvasive bioimaging.

Researchers build synthetic membrane channels out of DNA
Physicists at the Technische Universitaet Muenchen and the University of Michigan have shown that synthetic membrane channels can be constructed through "DNA nanotechnology." This technique employs DNA molecules as programmable building materials for custom-designed, self-assembling, nanometer-scale structures. The researchers present evidence that their nature-inspired nanostructures may also behave like biological ion channels. Their results could mark a step toward applications of synthetic membrane channels as molecular sensors, antimicrobial agents, and drivers of novel nanodevices.

King's College London finds rainbows on nanoscale
New research at King's College London may lead to improved solar cells and LED-displays. Researchers from the Biophysics and Nanotechnology Group at King's, led by Professor Anatoly Zayats in the department of Physics have demonstrated in detail how to separate colours and create 'rainbows' using nanoscale structures on a metal surface.

Lava dots: Rice makes hollow, soft-shelled quantum dots
Serendipity proved to be a key ingredient for the latest nanoparticles discovered at Rice University. The new "lava dot" particles were discovered accidentally when researchers stumbled upon a way to use molten droplets of metal salt to make hollow, coated versions of a nanotech staple called quantum dots. The results appear online this week in the journal Nanotechnology.

Rice unveils super-efficient solar-energy technology
Rice University scientists have unveiled a revolutionary new technology that uses nanoparticles to convert solar energy directly into steam. The new "solar steam" method from Rice's Laboratory for Nanophotonics is so effective it can even produce steam from icy cold water. Details of the solar steam method were published online today in ACS Nano. The technology's inventors said they expect it will first be used in sanitation and water-purification applications in the developing world.

Study reveals clues to cause of hydrogen embrittlement in metals
Hydrogen can easily dissolve and migrate within metals to make these otherwise ductile materials brittle and more prone to failures. Now, researchers at McGill University in Montreal and Ecole Polytechnique Federale de Lausanne in Switzerland, have shown that the physics of hydrogen embrittlement may be rooted in how hydrogen modifies material behaviors at the nanoscale. In a study published in Nature Materials, they present a model that can accurately predict the occurrence of hydrogen embrittlement.

Fabrication on patterned silicon carbide produces bandgap to advance graphene electronics
By fabricating graphene structures atop nanometer-scale "steps" etched into silicon carbide, researchers have for the first time created a substantial electronic bandgap in the material suitable for room-temperature electronics. Use of nanoscale topography to control the properties of graphene could facilitate fabrication of transistors and other devices, potentially opening the door for developing all-carbon integrated circuits.

Breakthrough nanoparticle halts multiple sclerosis
In a breakthrough for nanotechnology and multiple sclerosis (MS), a biodegradable nanoparticle delivers an antigen that tricks the immune system and halts MS in mice. The approach, the first that doesn't suppress the immune system, is being tested in a clinical trial for MS patients, but with white blood cells delivering the antigen. The nanoparticle is an easier, cheaper option and can be used in other immune-related diseases including Type 1 diabetes, food and airway allergies.

New program draws young artists into science
Artists and scientists often share a common goal: making the invisible visible. Yet artistically talented students, especially girls, often shy away from scientific careers. A new four-year, $1.2 million program led by the University of Alaska Fairbanks blends the art, biology and physics of color into a series of summer academies, science cafes and activity kits designed to inspire art-interested students to enter careers in science.

These bots were made for walking: Cells power biological machines
They're soft, biocompatible, about 7 millimeters long -- and, incredibly, able to walk by themselves. Miniature "bio-bots" developed at the University of Illinois are making tracks in synthetic biology. The walking bio-bots demonstrate the Illinois team's ability to forward-engineer functional machines using only hydrogel, heart cells and a 3-D printer. The bio-bots could be customized for specific applications in medicine, energy or the environment.

Physicists skirt thermal vibration, transfer optical signal via mechanical oscillator
Using tiny radiation pressure forces, physicists converted an optical field, or signal, from one color to another, aided by a "dark mode." The conversion occurs through the coupling between light and a mechanical oscillator, without interruption by thermal mechanical vibrations.

Wax-filled nanotech yarn behaves like powerful, super-strong muscle
New artificial muscles made from nanotech yarns and infused with paraffin wax can lift more than 100,000 times their own weight and generate 85 times more mechanical power during contraction than the same size natural muscle, according to scientists at the University of Texas at Dallas and their international team. The artificial muscles are yarns constructed from carbon nanotubes.

NIST study suggests carbon nanotubes may protect DNA from oxidation
NIST researchers have provided evidence that single-wall carbon nanotubes may help protect DNA molecules from damage by oxidation, which can lead to mutations. More studies are needed to see if the in vitro protective effect of nanotubes reported in the laboratory also occurs in vivo, that is, within a living organism.
