Microscopy News
CONFOCAL MICROSCOPE
Dec 1, 2005 — Visitors to the Web site of Olympus Life and Material Science Europa GmbH can view a demonstration of the company’s Lext UV-laser scanning confocal microscope for precise surface analysis. It depicts the real-time 3-D observation and measurement of samples placed on the microscope stage without pretreatment. Numerous application images in 2- and 3-D, from metal corrosion on automotive parts to the measurement of the laser mark depth for bare wafer production, are presented. The device’s image...
Improving Nanopositioning Resolution
Dec 1, 2005 — Nanopositioning is a basic requirement in virtually all areas of nanotechnology research. And, because it implies very small motions controlled with a high degree of accuracy, it seems intuitive to seek a specification of a nanopositioner’s...
Maskless Photolithography May Offer Cost Advantage
Dec 1, 2005 — Conventional lithography achieves sub-100-nm features by using short-wavelength light, immersion technology and optical enhancements such as phase-shift masks. But the dramatically increasing cost of the latter makes alternative, maskless...
Microscope Setup Rapidly Images Plasmon Sensor Array
Dec 1, 2005 — When it comes to genomic and proteomic arrays, researchers want fast measurements and techniques free of fluorescent labels. These characteristics, noted University of California, Berkeley, bioengineering professor Luke P. Lee, can reduce the time...
Microscopy of Mother-of-Pearl Suggests Novel Formation Mechanisms
Dec 1, 2005 — The iridescent substance called nacre, or mother-of-pearl, is of particular interest to materials scientists because this layered arrangement of CaCO3 crystal platelets is some 3000 times more resistant to fracture than pure crystal. An...
MICROSTRUCTURES
Dec 1, 2005 — Released by Präzisionsoptik Gera GmbH, the eight-page catalog “Standard-Microstructures” provides technical specifications for eyepiece graticules, including the crosshair types for integration into standard microscope eyepieces, and the scale types...
Nanosheets Might Make Microlasers
Dec 1, 2005 — Researchers at the University of California, Davis, have created planar clusters of CdSe nanocrystals that emit polarized light in the plane of the cluster. The discovery could lead to nanostructures that emit light, such as lasers and LEDs; absorb...
OEM PROTOTYPES
Dec 1, 2005 — Prior Scientific has issued a four-page brochure titled “OEM Solutions,” which describes its design, development, assembly, manufacturing and testing capabilities. The full-color document says that the company’s ISO 9001:2000-certified facility is...
Optical Profiler Technology Enables High-Magnification Measurement Through Transmissive Materials
Dec 1, 2005 — For decades, high-performance optical profilers have been evolving to adapt white-light interferometry to research and production applications in materials science, semiconductors, optics and the biological sciences. However, a limitation that...
Optical Tweezers Study Alters Einstein’s Theory of Motion
Dec 1, 2005 — Brownian motion, first described theoretically by Albert Einstein 100 years ago, is the concept that the irregular motion of particles in a fluid is caused by random thermal agitation of the surrounding molecules. Since then, scientists have...
Photoluminescence/Raman System Images Nanotubes
Dec 1, 2005 — Using a setup that enables simultaneous high-resolution photoluminescence and Raman imaging, scientists at Universität Tübingen in Germany and at the University of Rochester in New York are probing single-walled carbon nanotubes. Coupled with the...
Silica Nanotubes Loaded with Laser Dyes
Dec 1, 2005 — A team of scientists in South Korea has used a sol-gel process to fabricate color-tunable silica nanotubes that incorporate functional laser dyes. The investigators suggest that the one-dimensional structures may form the basis of new nanoscale...
Tip Design Offers Aperture and Apertureless Advantages
Dec 1, 2005 — A design for a metallic tip probe for scanning near-field optical microscopy promises the benefits of both aperture and apertureless techniques. The scientists at Gifu University in Japan who conceived the probe geometry suggest that it should yield...

Nov 29, 2005 — PALO ALTO, Calif., Nov. 29 -- Agilent Technologies Inc., a maker of test and measurement equipment with applications in electronics, communications, life sciences and chemical analysis, today announced that it has acquired privately held Molecular...
Molecular Switch Control Method Devised
Nov 28, 2005 — UNIVERSITY PARK, Pa., Nov. 28 -- A team of scientists at Penn State, Rice University and the University of Oregon have developed a way to control single-molecule switches by engineering their design and environment. The discovery, which is an...
News Briefs
Nov 25, 2005 — Sense Holdings Inc., a Fort Lauderdale, Fla., developer of biometric and explosives detection security technologies, has filed a patent involving handheld explosives detectors based on microelectromechanical sensors, or MEMS. The company is also...
Ohio State Installs Microscope That Can Magnify 30 Million Times
Nov 22, 2005 — COLUMBUS, Ohio, Nov. 22 -- The Ohio State University is one of the first customers in the world to receive a new microscope capable of magnifying up to 30 million times, enabling researchers to examine materials at the atomic scale (sub-angstrom)....
'Light Field Camera' Banishes Fuzzy Photos
Nov 8, 2005 — STANFORD, Calif., Nov. 8 -- Computer scientists are bringing photographic technology into sharper focus. Ren Ng, a Stanford University computer science graduate student in the lab of Pat Hanrahan, the Canon USA professor in the school of...
