Unique THz 'fingerprints' will identify hidden explosives from a distanceA major breakthrough in remote wave sensing by a team of Rensselaer Polytechnic Institute researchers opens the way for detecting hidden explosives, chemical, biological agents and illegal drugs from a distance of 20 meters.The new, all-optical system, using terahertz (THz) wave technology, has great potential for homeland security and military uses because it can "see through" clothing and packaging materials...

Physicists at the National Institute of Standards and Technology (NIST) have demonstrated an ion trap with a built-in optical fiber that collects light emitted by single ions (electrically charged atoms), allowing quantum information stored in the ions to be measured. The advance could simplify quantum computer design and serve as a step toward swapping information between matter and light in future quantum networks.Described in a forthcoming issue of Physical Review Letters,* the new device...

TROY, Mich., June 16 /PRNewswire/ -- ilumisys, Inc., (www.ilumisys.com) developer and producer of next-generation solid-state lighting technology, announced today that channel partner Ecogreen Solutions Inc. has installed light-emitting diode (LED) light tubes at Holiday Inn Old Town in San Diego and Casa Romantica in San Clemente, Calif., to reduce energy costs and maintenance requirements. Los Angeles-based Ecogreen Solutions replaced T-8 fluorescent lights with ilumisys MK-1 LED light...

Counterfeit products create losses in the billions each year. Beside the economic damages, all too often additional risks arise from the poor materials and shoddy workmanship of "knock-off artists". Yet with the aid of fluorescing dyes, materials can be individually tagged and identified with certainty.For quite some time now, product piracy has been affecting more than just consumer goods, like watches and designer clothing. The producer industry also has to combat bogus and...

PORT MATILDA, Pa., June 7 /PRNewswire/ -- QBC Diagnostics is pleased to announce the release of the SureFocus Microscope Slide, a breakthrough in the detection of tuberculosis bacteria. The SureFocus slide is a high-grade glass microscope slide that is printed with a patent pending, crosshair-styled smear guide. The guide contains a dye that fluoresces under the same light wavelengths that excite Auramine stains, which are used to stain tuberculosis Acid Fast Bacilli (AFB) for review with...

BEDFORD, Mass., May 5 /PRNewswire/ -- VisEn Medical Inc., a leader in fluorescence imaging from research through medicine, announced today the commercial launch of its new VivoTag(®) 645 red fluorescent dye for optimized labeling of biomolecules in a broad range of in vitro and in vivo research applications. The new VivoTag 645 represents VisEn's first agent offering in the lower-red wavelengths, enabling optimized and integrated imaging applications in both in vivo and in vitro...

Scientists at Carnegie Mellon University's Department of Chemistry and Molecular Biosensor and Imaging Center (MBIC) are advancing the state-of-the-art in live cell fluorescent imaging by developing a new class of fluorescent probes that span the spectrum "” from violet to the near-infrared. The new technology, called fluoromodules, can be used to monitor biological activities of individual proteins in living cells in real time. At the 239th national meeting of the American Chemical...

BEDFORD, Mass., March 25 /PRNewswire/ -- VisEn Medical Inc., a leader in fluorescence imaging from research through medicine, announced today the commercial launch of its new GastroSense(TM) 750 fluorescence agent for imaging gastric motility and related drug effects in vivo. Gastric motility, or the rate of nutrient transport through the gastrointestinal tract, is an established measure of overall gastric health, specific gastric disorders, and general physiologic health related to...

Scrutinizing a single molecule for more than a few milliseconds used to require effectively "stapling" it down, inhibiting its normal behavior. Now, using a technique recently developed in their lab, Stanford chemists have for the first time confined a protein (one involved in photosynthesis), observed its behavior for more than a second and learned things about it that could influence solar energy technology and biofuels.For the first time, researchers have been able to confine and...

BEDFORD, Mass., March 11 /PRNewswire/ -- VisEn Medical Inc., a leader in fluorescence in vivo imaging from research through medicine, announced today the commercial launch of its new VivoTag® 680 XL fluorescent dye for labeling biomolecules in a broad range of in vitro and in vivo imaging applications. VisEn's new near-infrared label, VivoTag® 680 XL, adds an additional imaging label to its current portfolio of VivoTag fluorescent dyes which are used to label specific biomolecules...
