Movies show nanotubes bend like sluggish guitar strings
In an exciting advance in nanotechnology imaging, Rice University scientists have discovered a way to use standard optical microscopes and video cameras to film individual carbon nanotubes — tiny cylinders of carbon no wider than a strand of DNA. view more (2006-06-28)
One-Touch Pathology Slide Microscanning
In clinical pathology the diagnostic process is a multi-step process where the pathologist views a prepared tissue sample on an optical microscope. The pathologist switches repeatedly between a low magnification, wide field view of the whole sample to a high magnification, narrow field view of selected portions of the sample. A diagnosis is made... view more... (2004-02-19)
McMaster University unveils world's most advanced microscope
The most advanced and powerful electron microscope on the planet-capable of unprecedented resolution-has been installed in the new Canadian Centre for Electron Microscopy at McMaster University. view more (2008-10-21)
Using light to detect breast cancer spread - groundbreaking imaging technology
Surgeons of the future may use light to tell whether breast cancer has spread, clinical research fellow Andrew Lee told a news briefin at the 3rd European Breast Cancer Conference in Barcelona. view more (2002-03-18)
Superlubricant effect explained using new friction force sensor
Research conducted in the Netherlands has revealed a previously unknown effect in graphite. The discovery was made by Martin Dienwiebel using the Tribolever, a highly-sensitive friction force microscope which he had developed himself. Dienwiebel has termed the effect superlubrication and this effect probably explains why graphite is such a good... view more... (2003-04-11)
Polarization holographic device using photoreactive polymer liquid crystals
Photo-control of molecular orientation of polymer materials is of great interest for the development of highly functionalized holographic optical devices. view more (2005-10-19)
UCSB researchers develop hybrid silicon evanescent laser
In what promises to be an important advance, researchers at the University of California, Santa Barbara have developed a novel laser by bonding optical gain layers directly to a silicon laser cavity. view more (2005-11-16)
Plant Tomogram
New methods have emerged lately that allow to examine images of a living tissue without cutting it off an animal or a plant. The most advanced of them is the optical coherent tomography (OCT) method. The OCT device has been built and tried on plants by scientists from Nizhni Novgorod. Living tissues are turbid. They are almost impervious to the... view more... (2004-03-02)
Looking through the eyes of a mouse, scientists monitor circulating cells in its bloodstream
A team of researchers from the Wellman Center for Photomedicine at Massachusetts General Hospital (MGH) and Harvard Medical School (HMS) have developed an optical device that allows them to peer through the eyes of a mouse and monitor the cells passing through its bloodstream. view more (2007-12-04)
UGA biomedical engineer publishes on 'super-resolution' video imaging
A crucial tool in the evolution of scientific capability in bioscience, the fluorescence microscope has allowed a generation of scientists to study the properties of proteins inside cells. view more (2009-05-05)
Hanover Trade Fair 2003: Getting to grips with optical fibres
A vacuum gripper mounts optical waveguides exactly right on the micrometre Microtechnological precision components from the production line - up to date, the realisation of this vision lacked the tools and technologies for automated manufacturing. Therefore, the aim of the research project „MELEMECH", sponsored by the federal German... view more... (2003-04-07)
New Optical Antenna Brings Massive Benefits to Wireless Networks, Household Electronics and Longer Distance Data Transfer
A new optical antenna, developed by researchers at the University of Warwick, will bring significant benefits to credit card payments, wireless networks, household electronics and longer distance data transfer. The device was developed by Professor Roger Green and Roberto Ramirez-Iniguez, in the University of Warwick`s Engineering Department. It... view more... (2002-11-07)
Cancer diagnosis: Now in 3-D
University of Washington researchers have helped develop a new kind of microscope to visualize cells in three dimensions, an advance that could bring great progress in the field of early cancer detection. The technique could also bridge a widening gap between cutting-edge imaging techniques used in research and clinical practices, researchers said. view more (2009-02-10)
A technological breakthrough for radio astronomy - Astronomical observations via high-speed data link
To carry out simultaneuos observations with several telescopes and transform the combined data into pictures from distant galaxies has so far been a cumbersome procedure which often has taken a long time. Now a breakthrough has been achieved by way of the installation of optical fibre links between the observatories and the universities who have... view more... (2004-01-26)
CT colonoscopy has 90 percent agreement rate with optical colonoscopy
Nearly 90% of colon polyps greater than or equal to 6 mm in size detected at CT colonoscopy were demonstrated to represent true polyps at subsequent optical colonoscopy (the traditional method of viewing the colon and removing precancerous growths). view more (2007-05-07)
Electric Nudge toward Self-organization
In search of materials with nonlinear optical properties Window panes and eyeglass lenses that get darker as it gets brighter are especially great in the summer. Their secret lies in optical properties that change as the light intensity changes - nonlinear optical properties. Such materials are also of interest as optoelectronic components. One... view more... (2002-03-07)
Mobile microscopes illuminate the brain
The majority of our life is spent moving around a static world and we generate our impression of the world using visual and other senses simultaneously. view more (2009-11-03)
Bristleworms engineer optics - Photon02
Computer and optical communications engineers are now using optical structures to produce faster, more powerful, light-based processors and networks. However, according to Dr Andrew Parker from Oxford University, they are well behind the times as nature has been making these optical structures for at least 515 million years. He and his team are... view more... (2002-08-28)
Single-Crystal Semiconductor Wire Built into an Optical Fiber
An international science team from Penn State University in the United States and the University of Southampton in the United Kingdom has developed a process for growing a single-crystal semiconductor inside the tunnel of a hollow optical fiber. The device adds new electronic capabilities to optical fibers, whose performance in electronic devices... view more... (2008-03-13)
