Lasers Could Speed Cancer Testing
PHILADELPHIA, Feb. 18, 2010 – When a tissue biopsy is sent to a lab to be analyzed for cancer, it can take hours, days or even a week to get the results. Now, a new analysis technology developed by researchers i...
Shinshu U. Picks PET Crystals
SINGAPORE, Feb. 17, 2010 – Zecotek Photonics Inc.’s LFS scintillation crystals have been selected by Shinshu University in Japan for trials in its next-generation positron emission tomography (PET) medical i...
Nanobubbles ‘Jackhammer’ Cancer
HOUSTON, Texas, Feb. 5, 2010 – Using lasers and nanoparticles, scientists at Rice University discovered a new technique for singling out individual diseased cells and destroying them with tiny explosions. The scientists used lasers to make ‘nanobubbles’ by zapping gold...
Photonics West 2010 Sets Records
SAN FRANCISCO, Feb. 5, 2010 — SPIE Photonics West completed its debut at the Moscone Center in San Francisco last week with the final attendance count at 18,327, a record for the event. The new venue was a hit with attendees, and provided welcome room for growth. Both the...
Cell Communications Very Complex
NEW HAVEN, Conn., Feb. 4, 2010 – US scientists have performed an advanced study of structures inside live cells using total internal reflection fluorescence (TIRF) microscopy. The experiment, which was carried out...
How ‘Random’ Lasers Work
SALT LAKE CITY, Jan. 25, 2010 – When University of Utah scientists discovered a new kind of laser that was generated by an electrically conducting plastic or polymer, no one could explain how it worked, and some d...
Single Cycle of Light Pulsed
KONSTANZ, Germany, Jan. 6, 2010 -- Extremely short laser pulses – the duration of only one cycle of light – have been generated at the 1.5-µm wavelength used to transmit data, an achievement that could benefit frequency metrology and the ultrafast sciences such as ultrafast optical...
Adaptive Optics in Biological Imaging with Two-Photon Microscopy
Dec 1, 2009 — Cutting-edge biological microscopy has enabled researchers to explore tissue at the subcellular level in vivo. Having the ability to observe physiological processes in vivo has led to breakthroughs in our understanding of cancer, eye disease and...
T Cell Trigger: Sheer Force
BOSTON, Nov. 3, 2009 – An array of techniques including optical tweezers were used to find the "switch" that can swiftly change a T cell – a white blood cell that patrols the bloodstream and organs for signs of disease – from jury to executioner. Revealing this "missing...
Spectros Names Distributors
Oct 19, 2009 — Spectros of Portola Valley, Calif., a developer of advanced molecular sensing and imaging devices for detecting ischemia and cancer, announced it has signed exclusive distribution deals for its T-Stat VLS tissue oximeter and sensors. Australia-based...
Cells Respond to Laser Light
SAN FRANCISCO, Sept. 15, 2009 – For the first time, researchers have imported a light-controlled “on-off switch” from plants into a mammalian cell to instantly control a variety of cell functions by creating a hybrid protein that causes mouse cells to move in response to laser...
Blue Bananas Linked to Cell Death
INNSBRUCK, Austria, & NEW YORK, Sept. 10, 2009 – Bright blue luminescent rings found under UV light on the peels of very ripe bananas hold promise for studying how organisms rid themselves of dying cells, according to chemists in the US and Austria.
Biosensor Images Tumors
CHARLOTTESVILLE, Va., Aug. 12, 2009 — A new oxygen nanosensor created by coupling a light-emitting dye with a biopolymer simplifies the imaging of oxygen-deficient regions of tumors, said chemists at the University of Virginia who developed the material. Such tumors are associated with...
Viralytics strengthens portfolio
Jun 1, 2009 — In Sydney, Australia, Viralytics Ltd. has received a US patent for the use of Echoviruses, including the proprietary Evatak formulation of Echovirus Type 1, to treat all cancers expressing the integrin a2b1 molecule. Included are ovarian, prostate...
Imaging at 6 million fps
LOS ANGELES, May 1, 2009 – Engineers at UCLA have developed a (video) camera that captures images in real time at 6 million fps, or 1000 times faster than its predecessors. It may be used for flow cytometry to diagnose cancer.
Tool Aims to Reduce Biopsies
BOZEMAN, Mont., March 30, 2009 -- A handheld microscope that uses laser light to form an image of the skin's cellular structure could someday reduce the number of biopsies needed to diagnose skin cancer. Biopsies -- invasive, often painful procedures to remove skin samples for...
Provost Picked for Power Post
BALTIMORE, Md., March 13, 2009 -- Johns Hopkins University Provost and electrical engineer Kristina M. Johnson will be nominated to serve as undersecretary of the Department of Energy, President Barack Obama announced yesterday. If confirmed by the Senate as expected, Johnson...
BiOS Hot Topics Lives Up to Its Name
Jan 26, 2009 — In his opening remarks, Sergio Fantini, the moderator of Saturday night’s BiOS Hot Topics session, noted that the evening’s talks represented the state of the art in biomedical optics. And indeed they did. Reflecting a diverse set of interests –...
How to Get Grant and Venture Funding
Jan 12, 2009 — Your Research Needs the Right Acronym When I went to grad school, I assumed that I needed to do good research, but no one told me about the importance that acronyms have in the scientific community. Acronyms are absolutely necessary to call...
Chirped Fiber Improves Pulse
BERLIN, Oct. 29, 2008 -- By introducing a radial chirp into a photonic crystal, researchers in Germany and Russia have developed a novel optical fiber that can transmit ultrashort light pulses with very little distortion over extended distances. The fiber could prove useful...
Center Aims for Smarter LEDs
TROY, N.Y., Oct. 8, 2008 -- A new research center that aims to replace existing lighting with smarter and greener LEDs and integrate them with optical wireless communications has been funded by a five-year, $18.5 million grant from the National Science Foundation (NSF). The...
Biosensors Measure Molecules
CHAMPAIGN, Ill., Sept. 24, 2008 -- A new class of disposable, photonic crystal biosensors has been developed that can detect protein-DNA interactions. By examining the light reflected from the crystal, researchers can tell when molecules are added to or removed from the crystal...
Cutting Cancer by Color
BOSTON, Aug. 21, 2008 — The key to a successful cancer surgery is the removal of all of the diseased tissue, but sometimes tumor boundaries can be difficult to track. However, researchers in Massachusetts have developed a new imaging system that highlights cancerous tissue...
Cancer Probe Trials Funded
AUSTIN, Texas, Aug. 19, 2008 -- A new grant will allow a researcher to continue developing and testing a device that uses light to detect skin cancer without the need for an invasive biopsy. University of Texas at Austin biomedical engineer James Tunnell has been awarded a...
On-chip Microscope Developed
PASADENA, Calif., July 29, 2008 -- Computer chip technology has been combined with microfluidics to create a tiny lenseless microscope small enough to fit on a fingertip and with magnifying power that rivals top optical microscopes. The high-resolution optofluidic microscope can use...
