(PhysOrg.com) -- How do individual cells or proteins react to changing pH levels? Researchers at the MESA+ Institute for Nanotechnology at the University of Twente, The Netherlands, have developed a technique for ‘gently` adjusting pH: in other words, without damaging biomolecules. This should soon allow them to measure the activity of a single enzyme as a function of pH. http://www.physorg.com/news180726696.html Chemistry Tue, 22 Dec 2009 18:20:01 EST news180726696 Sandia National Laboratories scientists have developed tiny glitter-sized photovoltaic cells that could revolutionize the way solar energy is collected and used. http://www.physorg.com/news180713660.html Technology Tue, 22 Dec 2009 14:14:56 EST news180713660 (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) -- 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 Johns Hopkins biomedical engineers, working with colleagues in Korea, have produced a laboratory chip with nanoscopic grooves and ridges capable of growing cardiac tissue that more closely resembles natural heart muscle. http://www.physorg.com/news180116595.html Nanotechnology Tue, 15 Dec 2009 16:24:23 EST news180116595 (PhysOrg.com) -- A new microscopic system devised by researchers in MIT's Department of Materials Science and Engineering could provide a novel method for moving tiny objects inside a microfluidic chip, and could also provide new insights into how cells and other objects are transported within the body. http://www.physorg.com/news180029015.html Physics Mon, 14 Dec 2009 16:08:06 EST news180029015 A team led by Yale University researchers has used nanosensors to measure cancer biomarkers in whole blood for the first time. Their findings, which appear December 13 in the advanced online publication of Nature Nanotechnology, could dramatically simplify the way physicians test for biomarkers of cancer and other diseases. http://www.physorg.com/news179932985.html Nanotechnology Sun, 13 Dec 2009 13:23:58 EST news179932985 (PhysOrg.com) -- What started out as 'blue-sky' thinking by a group of European researchers could ultimately lead to the commercial mass production of a new generation of optoelectronic components for devices ranging from mobile laboratories to mobile phones. http://www.physorg.com/news179765431.html Physics Fri, 11 Dec 2009 14:51:12 EST news179765431 The Materials on the International Space Station Experiment (MISSE) 7, designed and built by the Naval Research Laboratory (NRL), launched aboard STS-129 on November, 16, for transport to the International Space Station. http://www.physorg.com/news179420757.html Space & Earth Mon, 07 Dec 2009 15:06:37 EST news179420757 (PhysOrg.com) -- Donhee Ham, Gordon McKay Professor of Electrical Engineering and Applied Physics, uses his personal energy and understanding of physics to design innovative integrated circuits. http://www.physorg.com/news179085037.html Physics Thu, 03 Dec 2009 20:50:02 EST news179085037 (PhysOrg.com) -- John Rinn, a researcher at Harvard Medical School, the Beth Israel Deaconess Medical Center, and the Broad Institute, overcame a rocky start in life through a passion for biology and discovered a new category of RNAs. http://www.physorg.com/news179084924.html Medicine & Health Thu, 03 Dec 2009 18:10:01 EST news179084924 (PhysOrg.com) -- An extraordinarily bright, extraordinarily long-lasting supernova named SN 2007bi, snagged in a search by a robotic telescope, turns out to be the first example of the kind of stars that first populated the Universe. The superbright supernova occurred in a nearby dwarf galaxy, a kind of galaxy that's common but has been little studied until now, and the unusual supernova could be the first of many such events soon to be discovered. http://www.physorg.com/news179002328.html Space & Earth Wed, 02 Dec 2009 19:30:02 EST news179002328 IBM scientists have created a one-step point-of-care-diagnostic test, based on an innovative silicon chip, that requires less sample volume, is significantly faster, portable, easy to use, and can test for many diseases, including one of world's leading causes of death, cardiovascular disease*. The results are so quick and accurate that a small sample of a patient's serum or blood, could be tested immediately following a heart attack, to enable the doctor to quickly take a course of action to help the patient survive. http://www.physorg.com/news177880059.html Chemistry Thu, 19 Nov 2009 19:08:24 EST news177880059 Just as fly paper captures insects, an innovative new device with nano-sized features developed by researchers at UCLA is able to grab cancer cells in the blood that have broken off from a tumor. http://www.physorg.com/news177771822.html Chemistry Wed, 18 Nov 2009 13:04:21 EST news177771822 Like other users of microfluidic systems, National Institute of Standards and Technology researcher Javier Atencia was faced with an annoying engineering problem: how to simply, reliably and most of all, tightly, connect his tiny devices to the external pumps and reservoirs delivering liquids into the system. While pondering this one day, he randomly picked up two magnets and began playing with them. As the magnets pulled apart and then snapped back together, Atencia realized that he had his solution. http://www.physorg.com/news177761689.html Physics Wed, 18 Nov 2009 11:00:02 EST news177761689
