Why Smaller is Stronger
BERKELEY, Calif., Jan. 8, 2008 -- For 50 years scientists have known that as structures made of metal get smaller -- on the scale of millionths of a meter or less -- they get stronger. Many theories have been proposed to explain the phenomenon, but only recently have new imaging techniques made it possible to see and record what's actually happening in tiny structures under stress. Andrew Minor of the Materials Sciences Div. at Lawrence Berkeley National Laboratory, with colleagues from Hysitron Inc. and the General Motors...
Laser Beam Sorts Cells
CAMBRIDGE, Mass., Dec. 13, 2007 -- Like water from a firehose levitates a beach ball, a new system uses a targeted beam of light to push certain types of cells up out of special "traps." The method could make separating particular cells from a sample faster, cheaper and easier, and...
Buckyball Formation Observed
ALBUQUERQUE, N.M., Nov. 28, 2007 -- A Sandia National Laboratories researcher looking for flaws in nanotube durability was unexpectedly able to experimentally confirm a hypothesis about how Buckyballs form. “We have now the first direct, in situ, experimental proof of the...
Award Funds STED Microscope
LOS ANGELES, Nov. 5, 2007 -- A $1.1 million award from the National Science Foundation will enable the California NanoSystems Institute at UCLA to acquire the first commercially available superresolution stimulated emission depletion (STED) confocal laser scanning microscope...
Microsystem Incubates Cells
BALTIMORE, Oct. 3, 2007 -- By integrating silicon microchip technology with a network of tiny fluid channels, some thinner than a human hair, engineers have developed a thumb-sized microincubator to culture living cells for lab tests. Researchers at The Johns Hopkins...
NIH Supports Microscopy
WALTHAM, Mass., and NEW HAVEN, Conn., Sept. 27, 2007 -- The National Institutes of Health (NIH) has awarded more than $5 million to two researchers working separately to advance the study of cancer, diabetes and neurological diseases by developing new microscopy techniques. NIH Director Elias A....
System May Spot Silent Killer
EVANSTON, Ill., Aug. 2, 2007 -- New optical technology shown to be effective in the early detection of colon cancer now appears promising for detecting pancreatic cancer, the fourth most common cause of cancer deaths in the US. Known as a silent killer, pancreatic cancer...
Studying a Splat in the Making
Jul 1, 2007 — The splat that droplets of plasma make when they strike a substrate is similar to the shape that pancake batter forms when it hits a hot griddle. In the past, scientists investigating plasmas have had only the splat to work with — a situation that...
STED Microscope Inventor to Receive Springer Prize
Jun 13, 2007 — This year’s recipient of the Julius Springer Prize for Applied Physics is Göttingen, Germany-based researcher Stefan W. Hell for his revolutionary discovery that resolutions far below the diffraction limit can be achieved in a fluorescence...
Surprising Superconductor Behavior Mapped at Nanoscale
PRINCETON, N.J., June 1, 2007 -- A customized microscope has allowed the observation that patches of superconductivity can exist in ceramic superconductors at higher temperatures than previously thought, a discovery that may help improve scientific understanding of resistance-free...
Metagenomics Will 'Transform' Microbiology
WASHINGTON, April 20, 2007 -- The emerging field of metagenomics, where the DNA of entire communities of microbes is studied simultaneously, presents the greatest opportunity -- perhaps since the invention of the microscope -- to revolutionize understanding of the microbial...
Teen's Spectrograph Wins $100K Science Scholarship
WASHINGTON, March 15, 2007 -- A 17-year-old girl who built an accurate spectrograph that identifies the specific characteristics, or "fingerprints," of different kinds of molecules was named the top winner of the Intel Science Talent Search award on Tuesday, receiving a $100,000...
Plans Developed for Lensless 'Ultimate Microscope'
SHEFFIELD, England, March 14, 2007 -- Scientists have developed an innovative way to take images of atoms in living cells without using a lens. They now plan to use the technique to develop the ultimate x-ray microscope, which could be used to take high-resolution 3-D images of any...
FEI Systems Selected for UCLA's California NanoSystems Institute
Jan 9, 2007 — The California NanoSystems Institute (CNSI) at the University of California, Los Angeles, has selected FEI Co. of Hillsboro, Ore., to supply three advanced transmission electron microscopes (TEM) for the institute's Electron Imaging Center for...
Rensselaer Licenses Microscope Technology to Thorlabs
Dec 13, 2006 — An innovative microscope technology invented by researchers at Rensselaer Polytechnic Institute in Troy, N.Y., has been licensed by Thorlabs Inc., a manufacturer of photonics products based in Newton, N.J. The device, called the adaptive scanning...
Max Planck Director Wins Innovation Award for Light Microscopy Work
Nov 29, 2006 — This year's 10th annual German Innovation Award -- the German President's prize for technology -- has been awarded to Göttingen-based scientist Stefan W. Hell. The director of the Max Planck Institute for Biophysical Chemistry received the 250,000...
Nanoparticles Viewed in 3-D
DAVIS, Calif., Nov. 28, 2006 -- A new x-ray microscope has been devised that can, for the first time, examine nanoparticles -- materials smaller in scale than one billionth of a meter -- in three dimensions. The device could be used to make better materials for electronics, optics...
Cutting Edge 'Nanoknife' Made
GAITHERSBURG, Md.. & BOULDER, Colo., Nov. 27, 2006 -- Researchers have designed a carbon nanotube knife that, in theory, would work like a cheese slicer, precisely cutting thin slices of cells. The scientists said the "nanoknife" could one day become a tabletop biology tool. The research team from...
Hybrid Microscope Combines Optics, Ultrafast Laser
BOULDER, Colo., Oct. 27, 2006 -- A new hybrid device that combines an optical microscope with an ultrafast laser could be used to simultaneously image both the electronic and physical patterns in devices such as nanotransistors or to identify the chemicals or elements that comprise...
Nanopoint Appoints M. Powell as Chief Scientist
Oct 25, 2006 — Nanopoint Inc., a Honolulu-based biotech company developing a better microscope, has hired Michael Powell, a researcher in the fields of catalytic antibodies, electrochemiluminescence and cell-based assays, as its chief scientist. Powell co-founded...
New Lithography Method Creates Molecule-Sized Images
EVANSTON, Ill., Sept. 29, 2006 -- Ever since the invention of the first scanning probe microscope in 1981, researchers have believed the powerful tool would someday be used for the nanofabrication and nanopatterning of surfaces in a molecule-by-molecule, bottom-up fashion. Despite...
New 'Superlens' Reveals Hidden Nanostructures
AUSTIN, Texas, Sept. 18, 2006 -- In a development that could enhance near-field microscopy, a 'superlens' made of a thin film of silicon carbide sandwiched between two layers of silicon oxide has enabled the first direct near-field optical images. Integrating a superlens into a...
Alis Acquired by Carl Zeiss SMT
OBERKOCHEN, Germany, Sept. 14, 2006 -- Carl Zeiss SMT AG this week closed its acquisition of Peabody, Mass.-based Alis Corp., a nanotechnology startup developing scanning ion microscopes and imaging systems. Specific terms of the deal were not disclosed. Carl Zeiss SMT, a provider of...
Optofluidic Microscope Invented
PASADENA, Calif., Sept. 11, 2006 -- The old optical microscopes that everyone used in high school biology class may be a step closer to the glass heap. Researchers at the California Institute of Technology have announced their invention of an optofluidic microscope that uses no lens...
Resolution of Fluorescing Microscope Reaches 15nm
GÖTTINGEN, Germany, Aug. 22, 2006 -- Scientists have used a new trick involving fluorescent dyes to surpass their own STED (stimulated emission depletion) microscope resolution records set in April and further distance themselves from limits imposed by Abbe's Law. Scientists at the...
