Biophotonics News
Light-Activated ‘Living Crystals’ Created
NEW YORK, Feb. 4, 2013 — Birds of a feather flock together, but what causes these flocks to form and move in a particular way has always been a fundamental question in nature. Now, however, a method using “living crystals” that behave in near-lifelike ways when activated by blue light, could provide the answer.
BSI Presents Awards for Advances in Ultrafast Research
EAST LANSING, Mich., Feb. 1, 2013 — Dr. Jan Rothhardt and professor Georgios Alexandrakis will be recognized for their contributions to ultrafast research during an awards reception hosted by Biophotonic Solutions Inc. (BSI) during Photonics West 2013 in San Francisco.
Defying expectations, x-ray laser supercharges atoms
MENLO PARK, Calif. – Using a single flash from the world’s most powerful x-ray laser, researchers have stripped a record number of electrons from xenon atoms, creating a “supercharged,” strongly positive state at energies previously thought too low....
QDs Are Entering the Mainstream
Feb 1, 2013 — Since their discovery in the 1980s, quantum dots have been quietly gaining momentum, making slow but steady headway in applications from displays and lighting to photovoltaics and health care. Unique and versatile, quantum dots (QDs) are no longer...
Tiny probes dramatically boost Raman signals
ST. LOUIS – Novel gold nanoparticles can goose the signal from Raman reporters, or molecules whose jiggling atoms respond to a probe laser by scattering light at characteristic wavelengths. The discovery could lead to better-targeted drug delivery and deeper...
Microimplant Controls Nerve Cells with a Laser
FREIBURG, Germany, and BASEL, Switzerland, Jan. 31, 2013 — A microimplant that can genetically modify specific nerve cells, control them with light stimuli and measure their activity simultaneously could pave the way for completely new experiments in neurobiology.
Laser Technique Unravels Spider Silk’s Mysteries
GLENDALE, Ariz., Jan. 30, 2013 — A noninvasive, noncontact laser light scattering technique may be the key to unraveling the secret behind spider silk’s strength.
Biolase Appoints Key Managers
IRVINE, Calif., Jan. 29, 2013 — Dental laser manufacturer Biolase Inc. announced this week two key senior management appointments to strengthen its overall operations and to promote its core dental product franchise.
Arresting Epileptic Seizures with Fiber Optics
IRVINE, Calif., Jan. 28, 2013 — Unpredictable epileptic seizures can now be stopped in their tracks with a new approach that activates optical fibers implanted in the brain when a computer system detects a real-time seizure.
Gooch & Housego Ink Q-Switch Deal with Han’s Laser
ILMINSTER, England, Jan. 28, 2013 — Gooch & Housego has signed a three-year contract to supply acousto-optic Q-switches to Han’s Laser of Shenzhen, China.
Iridex: Q4 Laser Sales Strong
MOUNTAIN VIEW, Calif., Jan. 24, 2013 — Iridex Corp.’s revenues in the fourth quarter of 2012 were stronger than expected, driven by a healthy uptick in laser system sales.
Nanolens Microscopes Detect Viruses Such as Flu
LOS ANGELES, Jan. 24, 2013 — As the flu spreads like wildfire across the US, quickly diagnosing patients with aches, pains, fever and chills has never been more important. A new optical microscopy method aims to do just that by using tiny liquid lenses that self-assemble around...
Optical Projection Moves from VIS to IR
UMEÅ, Sweden, Jan. 22, 2013 — A new imaging method enables optical projection tomography to be extended from the visible to the near-IR spectrum, allowing the study of different types of cells in one preparation and the use of different contrast agents. The findings could be...
Block Engineering to Develop QCL System with Pfizer
MARLBOROUGH, Mass., Jan. 21, 2013 — Block Engineering has partnered with Pfizer Inc. to develop a quantum cascade laser based infrared spectroscopy system for noncontact cleaning verification of vessels during pharmaceutical manufacturing.
GSI Expands in Medical Market with $82M Acquisition
BEDFORD, Mass., Jan. 16, 2013— GSI Group Inc. said its $82.5 million cash acquisition of NDS Surgical Imaging, a San Jose, Calif.-based producer of surgical and radiology displays, provides a substantial platform for the company’s growth in the medical market and expands...
Light-Activated Hydrogel Repairs Cartilage
BALTIMORE, Jan. 15, 2013 — Runners and knee pain sufferers, take heed. A new squishy biomaterial called a hydrogel could help repair damaged cartilage when activated with light, giving those achy joints some relief.
