Its operation principle is completely different from conventional devices, which opens up the possibility of a significantly reduced energy input requirement. The researchers report their work in Nature. http://www.imaging-git.com/news/new-type-laser Fri, 24 May 2013 03:57:00 +0000 http://www.imaging-git.com/news/heinrich-rohrer-co-inventor-scanning-tunneling-microscope-passed-away The co-inventor of the scanning tunneling microscope, Dr. Heinrich Rohrer, passed away on the evening of May 16, 2013. He was 79. Heinrich Rohrer, IBM Fellow and Nobel Laureate, joined the IBM Research Laboratory in Zurich, Switzerland, in December of 1963, where he worked for 34 years. After hiring a young scientist named Gerd Binnig in the late 1970s, the two started collaborating, brought closely together by their backgrounds in superconductivity and their fascination with atomic surfaces. The two scientists grew increasingly frustrated by the limits of the tools then available to study the distinct characteristics of atomic surfaces, so they decided to build their own, something that would be capable of seeing and manipulating atoms at the nanoscale level. http://www.imaging-git.com/news/heinrich-rohrer-co-inventor-scanning-tunneling-microscope-passed-away Thu, 23 May 2013 09:17:00 +0000 http://www.imaging-git.com/news/improved-imaging-technique-solve-key-puzzle-led-efficiency From the high-resolution glow of flat screen televisions to light bulbs that last for years, light-emitting diodes (LEDs) continue to transform technology. The celebrated efficiency and versatility of LEDs-and other solid-state technologies including laser diodes and solar photovoltaics-make them increasingly popular. Their full potential, however, remains untapped, in part because the semiconductor alloys that make these devices work continue to puzzle scientists. http://www.imaging-git.com/news/improved-imaging-technique-solve-key-puzzle-led-efficiency Thu, 23 May 2013 06:25:00 +0000 http://www.imaging-git.com/products/image-processing/visualize-quantum-behavior-large-molecules-real-time The group of Professor Markus Arndt at the University of Vienna, Austria, has shown the diffraction of single, massive molecules at a grating in an unambiguous demonstration of the wave-particle duality of quantum physics. http://www.imaging-git.com/products/image-processing/visualize-quantum-behavior-large-molecules-real-time Fri, 17 May 2013 08:56:00 +0000 http://www.imaging-git.com/products/light-microscopy/cobolt-calypso-491-nm-high-performance-dpss-laser-demanding-analytical-app The Swedish DPSS lasers manufacturer Cobolt has recently released a higher power version of its Cobolt Calypso 491nm.The laser is now available on the 05-01 Series single frequency platform with an output power of 200 mW CW.

This study describes an advanced stealth liposome approach of drug delivery, employing confocal laser scanning fluorescence microscopy to evaluate the selective targeting of macrophages. http://www.imaging-git.com/applications/improving-drug-delivery-macrophage-targeting Thu, 16 May 2013 11:06:00 +0000 http://www.imaging-git.com/news/scanning-electrochemical-microscopy-measuring-oxygen-consumption-individual-cells How active a living cell is can be seen by its oxygen consumption. The method for determining this consumption has now been significantly improved by chemists in Bochum. The problem up to now was that the measuring electrode altered the oxygen consumption in the cell's environment much more than the cell itself. "We already found that out twelve years ago," says Prof. Dr. Wolfgang Schuhmann from the Department of Analytical Chemistry at the Ruhr-Universität (Germany). "Now we have finally managed to make the measuring electrode an spectator." Together with his team, he reports in the "International Edition" of the journal Angewandte Chemie. http://www.imaging-git.com/news/scanning-electrochemical-microscopy-measuring-oxygen-consumption-individual-cells Tue, 14 May 2013 05:46:00 +0000 http://www.imaging-git.com/applications/unmask-hidden-without-probes-cars Fluorescence microscopy assumed a pivotal role in cell biology once it was possible to stain cell components selectively by fluorescing dyes. One of the first explorers of targeted stainings, Paul Ehrlich, had the idea that something that stains specifically should also kill specifically - which was associated with the term "magic bullet", the essential idea of chemotherapy. His group discovered Salvarsan, a tailored drug against syphilis - though not specific enough not to cause substantial side effects. http://www.imaging-git.com/applications/unmask-hidden-without-probes-cars Mon, 13 May 2013 11:00:00 +0000 http://www.imaging-git.com/news/x-ray-free-electron-lasers-observing-movement-electrons-around-atoms X-ray free-electron lasers (XFELs) produce higher-power laser pulses over a broader range of energies compared with most other x-ray sources. Although the pulse durations currently available are enormously useful for the study of materials, even shorter pulses are needed to observe features such as electrons at subatomic scales. Takashi Tanaka from the Riken SPring-8 Center has now proposed a theoretical pulse-amplification scheme that allows for the production of ultrashort x-ray pulses at extremely high energies. http://www.imaging-git.com/news/x-ray-free-electron-lasers-observing-movement-electrons-around-atoms Mon, 13 May 2013 07:01:00 +0000 http://www.imaging-git.com/products/image-processing/photonic-science-introduces-scmos-cameras-open-source-software Photonic Science has introduced a new range of sCMOS camera for microscopy and spectroscopy applications. http://www.imaging-git.com/products/image-processing/photonic-science-introduces-scmos-cameras-open-source-software Tue, 07 May 2013 06:14:00 +0000 http://www.imaging-git.com/news/2013-fei-image-contest FEI invites owners and users to submit their best images from an FEI instrument.

Medical researchers might realize a range of breakthroughs if they could look deep inside living biological cells, but existing methods for imaging either lack the desired sensitivity and resolution or require conditions that lead to cell death, such as cryogenic temperatures. Recently, however, a team of Harvard University-led researchers working on DARPA's Quantum-Assisted Sensing and Readout (QuASAR) program demonstrated imaging of magnetic structures inside of living cells. Using equipment operated at room temperature and pressure, the team was able to display detail down to 400 nanometers, which is roughly the size of two measles viruses. http://www.imaging-git.com/news/quantum-assisted-nano-imaging-living-organism Mon, 06 May 2013 08:07:00 +0000 http://www.imaging-git.com/news/analytik-jena-establishes-subsidiary-thailand Analytik Jena, a manufacturer of analytical instrumentation technology, life science instruments and optoelectronics, has established a new subsidiary, Analytik Jena Far East (Thailand) Ltd., giving it a presence in the Southeast Asian market.

The researchers have developed a new set of metrics for analyzing data acquired via small angle scattering (SAS) experiments with X-rays (SAXS) or neutrons (SANS). Among other advantages, this will reduce the time required to collect data by up to 20 times. http://www.imaging-git.com/news/new-metrics-x-ray-and-neutron-analysis-flexible-macromolecules Tue, 30 Apr 2013 08:01:00 +0000 http://www.imaging-git.com/news/transmission-electron-microscopy-imaging-nanoparticles-action The macroscopic effects of certain nanoparticles on human health have long been clear to the naked eye. What scientists have lacked is the ability to see the detailed movements of individual particles that give rise to those effects. In a recently published study, scientists at the Virginia Tech Carilion Research Institute invented a technique for imaging nanoparticle dynamics with atomic resolution as these dynamics occur in a liquid environment. The results will allow, for the first time, the imaging of nanoscale processes, such as the engulfment of nanoparticles into cells. http://www.imaging-git.com/news/transmission-electron-microscopy-imaging-nanoparticles-action Mon, 29 Apr 2013 09:07:00 +0000 http://www.imaging-git.com/news/new-imaging-technology-could-reveal-cellular-secrets Researchers have married two biological imaging technologies, creating a new way to learn how good cells go bad. "Let's say you have a large population of cells," said Corey Neu, an assistant professor in Purdue University's Weldon School of Biomedical Engineering. "Just one of them might metastasize or proliferate, forming a cancerous tumor. We need to understand what it is that gives rise to that one bad cell." http://www.imaging-git.com/news/new-imaging-technology-could-reveal-cellular-secrets Mon, 29 Apr 2013 07:30:00 +0000 http://www.imaging-git.com/news/ultra-high-resolution-microscopy-cellular-networks-close High-powered microscopic techniques give scientists a detailed view of a critical component of the cellular infrastructure. The cellular interior is criss-crossed by protein-based cables known as microtubules, each formed from 13 ‘protofilaments' composed of the protein tubulin. Microtubules are also associated with a host of other specialized proteins that help coordinate the transport of molecular cargoes and link microtubules to intracellular structures. http://www.imaging-git.com/news/ultra-high-resolution-microscopy-cellular-networks-close Fri, 26 Apr 2013 08:10:00 +0000 http://www.imaging-git.com/news/multilayer-laue-lenses-enable-studies-nanostructures-ultra-high-resolution Microscopes have been a centerpiece of experimental science since at least the 16th century, providing a window into the material world at extraordinarily small scales.
