Researchers at the Albert Einstein College of Medicine of Yeshiva University have developed a new approach for treating and healing skin abscesses caused by bacteria resistant to most antibiotics. The study appears in the journal PLoS One. http://www.physorg.com/news180724963.html Nanotechnology Tue, 22 Dec 2009 18:10:05 EST news180724963 Scientists in China are reporting an advance that may improve the natural wonders of wool - already regarded as the "wonder fabric" for its lightness, softness, warmth even when wet, and other qualities. They say the discovery could give wool a "brain," placing it among other "smart" fabrics that shake off wrinkles, shrinkage and "breathe" to release perspiration. The study is in ACS' Langmuir. http://www.physorg.com/news180705463.html Nanotechnology Tue, 22 Dec 2009 11:58:43 EST news180705463 At Berkeley Lab's National Center for Electron Microscopy it was revealed that single-stranded DNA can disperse bundles of single-walled carbon nanotubes into individual tubes and serve as guideposts for synthesizing platinum nanoparticles onto these tubes. http://www.physorg.com/news180644226.html Nanotechnology Mon, 21 Dec 2009 19:10:01 EST news180644226 (PhysOrg.com) -- Scientists at the U.S. Department of Energy`s Brookhaven National Laboratory have found a new way to use a synthetic form of DNA to control the assembly of nanoparticles - this time resulting in switchable, three-dimensional and small-cluster structures that might be useful, for example, as biosensors, in solar cells, and as new materials for data storage. The work is described in Nature Nanotechnology, published online December 20, 2009. http://www.physorg.com/news180624054.html Nanotechnology Mon, 21 Dec 2009 13:21:26 EST news180624054 (PhysOrg.com) -- Just like our roads, there is a lot of traffic within the cells in our bodies, because cell components, messenger molecules, and enzymes must also be brought to the right places in the cell. One of these transportation systems functions like a kind of railway: a system of molecular tracks is used to transport vesicles and their contents to their target destinations. http://www.physorg.com/news180602012.html Chemistry Mon, 21 Dec 2009 07:14:11 EST news180602012 (PhysOrg.com) -- Nanotechnology has already made it to the shelves of your local pharmacy and grocery: nanoparticles are found in anti-odor socks, makeup, makeup remover, sunscreen, anti-graffiti paint, home pregnancy tests, plastic beer bottles, anti-bacterial doorknobs, plastic bags for storing vegetables, and more than 800 other products. http://www.physorg.com/news180363327.html Physics Fri, 18 Dec 2009 12:56:24 EST news180363327 (PhysOrg.com) -- A new carbon support that greatly increases the durability of proton-exchange membrane fuel cells has been developed by scientists at Pacific Northwest National Laboratory and Princeton University. This new material significantly improves the stability of the fuel cell catalyst and will potentially lower the cost of these fuel cells. This breakthrough research hit number one on the most-downloaded list of Electrochemistry Communications articles this fall. http://www.physorg.com/news180286762.html Nanotechnology Thu, 17 Dec 2009 15:40:06 EST news180286762 In an advance that could help ease health and environmental concerns about the emerging nanotechnology industry, scientists are reporting development of technology for changing the behavior of nanoparticles in municipal sewage treatment plants - their main gateway into the environment. Their study was published in ACS' journal Environmental Science & Technology. http://www.physorg.com/news180191013.html Nanotechnology Wed, 16 Dec 2009 13:40:01 EST news180191013 (PhysOrg.com) -- Scientists at Georgia Tech have developed a nanolithographic technique that can produce high-resolution patterns of at least three different chemicals on a single chip at writing speeds of up to one millimeter per second. The chemical nanopatterns can be tailor-designed with any desired shape and have been shown to be sufficiently stable so that they can be stored for weeks and then used elsewhere. The technique, known as Thermochemical Nanolithography is detailed in the December 2009 edition of the journal Advanced Functional Materials. The research has applications in a number of scientific fields from electronics to medicine. http://www.physorg.com/news180162467.html Nanotechnology Wed, 16 Dec 2009 05:08:15 EST news180162467 (PhysOrg.com) -- Tiny nanoprobes have shown to be effective in delivering cancer drugs more directly to tumor cells - mitigating the damage to nearby healthy cells - and Purdue University research has shown that the nanoprobes are getting the drugs to right cellular compartments. http://www.physorg.com/news180027243.html Nanotechnology Mon, 14 Dec 2009 16:10:05 EST news180027243 Researchers at Rice University and Baylor College of Medicine (BCM) have created a single nanoparticle that can be tracked in real time with MRI as it homes in on cancer cells, tags them with a fluorescent dye and kills them with heat. The all-in-one particle is one of the first examples from a growing field called "theranostics" that develops technologies physicians can use to diagnose and treat diseases in a single procedure. http://www.physorg.com/news180022136.html Nanotechnology Mon, 14 Dec 2009 14:09:22 EST news180022136 A new optical sensor developed by the American National Institute of Standards and Technology was successfully tested by the Physikalisch-Technische Bundesanstalt (Germany) in the "magnetically best shielded room on Earth." The sensor does not need advanced cooling and is very small. Its suitability was proven for biomagnetic measurements in the picotesla range. So, magnetocardiographic measurement devices -- to be used as a supplement or an alternative to the ECG -- could become simpler and less expensive. http://www.physorg.com/news179751368.html Physics Fri, 11 Dec 2009 10:56:58 EST news179751368 (PhysOrg.com) -- One of the promises of nanomedicine is the design of tiny particles that can home in on diseased cells and get inside them. Nanoparticles can carry drugs into cells and tag cells for MRI and other diagnostic tests; and they may eventually even enter a cell's nucleus to repair damaged genes. Unfortunately, designing them involves as much luck as engineering. http://www.physorg.com/news179520620.html Nanotechnology Tue, 08 Dec 2009 19:00:01 EST news179520620 (PhysOrg.com) -- Using a nanoparticle from corn, a Purdue University scientist has found a way to lengthen the shelf life of many food products and sustain their health benefits. http://www.physorg.com/news179507163.html Nanotechnology Tue, 08 Dec 2009 15:08:43 EST news179507163 A team led by Yale University scientists has developed a way to rapidly manipulate and sort different cells in the blood using magnetizable liquids. The findings, which will be published the week of December 7 in the online edition of the Proceedings of the National Academy of Sciences, could dramatically improve the speed and sensitivity of tests used to detect cancer biomarkers, blood disorders, viruses and other diseases. http://www.physorg.com/news179423243.html Nanotechnology Mon, 07 Dec 2009 15:48:29 EST news179423243
