Microscopy News
Flexible Microscope Explores Deeply Hidden Cells
WYNNEWOOD, Pa., Nov. 8, 2011 — A tiny, flexible microscope allows surgeons to view living tissue in real time at the cellular level during regular endoscopy procedures, precisely pinpointing what should be immediately removed or treated. The device, dubbed a probe-based confocal laser endomicroscope and marketed by Paris-based Mauna Kea Technologies as Cellvizio, is designed to diagnose gastrointestinal and biliary diseases. A microimaging system located at the end of a catheter that is threaded through a...

Extreme Ultraviolet: A New Frontier for Lasers
Nov 1, 2011 — Advances in compact EUV lasers could benefit industries from semiconductor manufacturing to medicine. Compact lasers that operate in the extreme ultraviolet (EUV) wavelengths – 5 to 50 nm – are poised to offer new abilities to image,...
Holographic lithography boosts plasmonic nanogap array production
HOBOKEN, N.J. – A technique based on methods from holographic lithography has been developed to demonstrate a new approach for scaling up the fabrication of plasmonic nanogap arrays while simultaneously reducing costs and infrastructure. A team led by Dr. Stefan...
Lasers are sparking Poland’s photonics future
WARSAW, Poland – As far as science in Poland is concerned, Nicolaus Copernicus may forever be the center of the universe, but many luminous researchers orbit that center centuries after the great astronomer’s passing. WARSAW, Poland – Germany, the UK and...
Navitar Licenses HMC Tech. to Carl Zeiss
ROCHESTER, N.Y., Nov. 1, 2011 — Optical technology provider Navitar Inc. has announced a licensing agreement with German optics manufacturer Carl Zeiss MicroImaging GmbH. Under the terms of the agreement, Zeiss has license to Navitar’s Hoffman Modulation Contrast (HMC)...
Spectra-Physics Gets Imaging Patent
Nov 1, 2011 — Spectra-Physics of Santa Clara, Calif., a division of Newport Corp., has announced the issuance of US patent No. 7,962,046 for its DeepSee multiphoton imaging technology. Used in the Mai Tai DeepSee and the InSight DeepSee products, the technique...
Through thick and thin: Microscopy reveals fluid viscosity patterns
ITHACA, N.Y. – A high-speed microscopy technique explains the behavior of fluids by observing how micron-size suspended particles dance in real time. Knowledge of how fluids work will help scientists and engineers handle complex fluids ranging from biological...
WOP, U Southampton Develop Z Polarizers
Nov 1, 2011 — Workshop of Photonics (WOP) of Vilnius, Lithuania, has collaborated with the Optoelectronics Research Centre (ORC) at the University of Southampton in the UK to develop a direct laser writing technique for producing radial polarization converters....
Netherlands Nanoscopy Center Opens Oct. 27
LEIDEN, Netherlands, Oct. 24, 2011 — The Netherlands Centre for Electron Nanoscopy (NeCEN), a new microscopy facility with two highly advanced cryotransmission electron microscopes, will open its doors Oct. 27. Established through the collaboration of 10 academic partners, local and...
Tuning Viruses Creates Complex Biological Tissues
BERKELEY, Calif., Oct. 20, 2011 — A benign virus has been turned into an engineering tool for assembling structures that mimic collagen, considered one of the most important structural proteins in nature. Researchers say this process eventually could be used to manufacture materials...
Laser-Based Method Detects Optical Forces in Blood
WASHINGTON, Oct. 19, 2011 — A new laser-based analysis method can detect optical pressure differences among classes of blood cells, and it doesn't rely on prior knowledge, antibodies or fluorescent labels for discrimination. Scientists at the US Naval Research Laboratory...
Early Career Scientists Honored for Photonics Research
WASHINGTON, Oct. 14, 2011 — A physicist who made a breakthrough in the field of superconducting detectors and a scientist working on the development of nanophotonic devices for optical communications and on-chip biosensing are two of eight photonics-related researchers to each...
