Conductive Nanofibers Self-Organize Under Light
STRASBOURG, France, April 27, 2012 — New flexible nanofibers that can self-assemble under a flash of light combine the best advantages of two materials currently used to conduct electric current: metals and plastic organic polymers. The nanofibers can be integrated into electronic devices such as flexible screens and solar cells and are easier to fabricate and handle than carbon ones. They also can conduct electricity as well as the best metals, a feature that will enable them to be used in nanoscale electronic components. ...
Femtolaser ‘Scalpel’ Spares Surrounding Tissue
AUSTIN, Texas, April 25, 2012 — A small, flexible endoscopic medical device fitted with a femtosecond laser “scalpel” can remove diseased or damaged tissue while leaving healthy cells untouched.
New X-ray Scope Reveals 3-D Nanostructures
UPTON, N.Y., April 23, 2012 — A new full field transmission x-ray microscope now makes it possible to rapidly capture and integrate thousands of two-dimensional images to create digital three-dimensional constructs with high accuracy. The direct observation of structures...
Optical Technique Detects Malaria Early
TRIESTE, Italy, April 19, 2012 — Rapid detection of malaria, particularly in remote parts of the world, is not always possible because current methods are slow and require precise instrumentation and highly skilled microscopic analysis. Now, using a technique called secondary...
SERS Susses Out Salmonella
ATHENS, Ga., April 11, 2012 — In the future, even the smallest traces of salmonella and other foodborne pathogens may be easily detected using a technology known as surface-enhanced Raman scattering, or SERS.
Controlling Quantum Tunneling with Light
CAMBRIDGE, England, April 6, 2012 — For the first time, light was used to demonstrate quantum tunneling, pushing electrons through a classically impenetrable barrier.
Laser Built on a Silicon Chip
SINGAPORE, April 2, 2012 — A laser with a novel mirror design was fabricated on a silicon chip using III-V semiconductor materials — a step toward forward for high-speed optical communications and interconnects on electronics chips.
Silicon Optical Diode for Quantum Information
COLLEGE PARK, Md., April 2, 2012 — Ring resonators can be used to develop micro-optical diodes to replace or be compatible with their electronic counterparts for quantum information.
Defense, Security Show Targets Baltimore
Apr 1, 2012 — SPIE moves its DSS conference and trade show to the Charm City to maximize exposure to governmental agencies, military institutions and research organizations. At the mention of Baltimore, certain things come to mind: crab cakes, the Orioles, Camden...
Handheld rainbow could spawn multispectral tools
BUFFALO, N.Y. – A new kind of polymer that is cheap and easy to make and reflects many different wavelengths of light when viewed from a single perspective could form the basis of handheld multispectral imaging devices. “Such portable technology could...
Multiband Optical Filters Find Applications Outside Fluorescence
Apr 1, 2012 — Whether used for imaging cells or astronomical bodies, multiband filters can improve signal-to-noise ratio while reducing cost, size, and setup and data-acquisition times in optical systems and instruments. In the past, most optical filters had a...
The physics behind the fizz
Apr 1, 2012 — Gorgeous floral arrangements can really brighten up a party – particularly when they’re blooming in champagne flutes. In a process invisible to the naked eye, champagne bubbles take on a flowerlike structure around bubbles...
Tunable optical filter uses nanoantennas
CAMBRIDGE, Mass. – A new tunable color filter based on optical nanoantennas can precisely control color output, enabling its use for display and bioimaging applications and for marking currency. By precisely controlling the shape of the nanoantennas, engineers at...
Diatom Biosensor Could Detect Chemicals in Water
SEQUIM, Wash., March 30, 2012 — A biosensor made of fluorescent proteins that are embedded in the shell of microscopic marine algae called diatoms could help detect chemicals in water samples. The device could help produce nanomaterials that can solve sensing, catalysis and...
Novel Plasmonic Material Discovered
WEST LAFAYETTE, Ind., March 30, 2012 — Titanium nitride, the first nonmetal to be added to the short list of surface-plasmon-supporting materials, could bridge the gap between optics and electronics. The advance could point the way to a new class of optoelectronic devices with...
Quantum Plasmon Resonance Illuminated
STANFORD, Calif., March 29, 2012 — Plasmon resonance at the nanoscale, the phenomenon responsible for the vibrant hues of stained-glass windows, can kill cancer cells and has the potential to drive forward quantum optics and bioimaging, new research suggests. Plasmon resonance is...
Cell Repair Seen in Real Time
KARLSRUHE, Germany, March 29, 2012 — Cell membrane repair in a living organism was observed for the first time in real time using a high-resolution fluorescence imaging technique. The findings may contribute to the development of therapies for human myopathies and pave the way for new...
Nanostars Seen as Superior for SERS
HOUSTON, March 29, 2012 — Synthesized starfruit-shaped gold nanorods could strengthen applications that rely on surface-enhanced Raman spectroscopy.
Pacer to Distribute Optotune’s Lenses, Speckle Reducers
NEWBURY, England, March 27, 2012 — The optoelectronic components and assemblies supplier will distribute Zurich-based Optotune Inc.’s adaptive polymer-based optics.
Photoacoustic Imaging Moves into Clinic
ST. LOUIS, March 26, 2012 — Photoacoustic tomography, which combines the best qualities of ultrasound and light absorption, can now provide clinicians with multicontrast images of biological tissue several inches below the skin’s surface.
CU Boulder Imaging Tech Optioned
BOULDER, Colo., March 22, 2012 — The University of Colorado has completed an exclusive option agreement with Double Helix LLC of Boulder to develop its novel 3-D superresolution imaging technique.
Proteins Shine a Brighter Light on Cellular Processes
GRENOBLE, France, March 22, 2012 — A molecule capable of emitting turquoise light within living cells three times brighter than ever achieved could improve the sensitivity of cellular imaging.
Laser ‘Unprinter’ Vaporizes Toner
CAMBRIDGE, England, March 21, 2012 — A laser device that vaporizes photocopied ink from paper could soon be in offices worldwide.
