Fast and affordable genome sequencing has moved a step closer with a new solid-state nanopore sensor being developed by researchers at the University of Illinois. http://www.physorg.com/news163160102.html Nanotechnology Tue, 02 Jun 2009 11:15:32 EST news163160102 (PhysOrg.com) -- Over the past 5 years, researchers have been exploring the use of nanoscale pores as nucleic acid sequencing tools. In theory, such pores should generate a unique response characteristic of each of the four nucleotide bases as a piece of DNA moves through the pore. http://www.physorg.com/news157378086.html Nanotechnology Fri, 27 Mar 2009 13:14:12 EST news157378086 Molecular biologists, including the cool dudes from CSI, use gel electrophoresis to separate DNA fragments from each other in order to analyze the DNA. A team of researchers under the leadership of Vici winner Serge Lemay, has now shown for the first time how the gel influences the movement of the DNA. The researchers drove a single DNA molecule through a nanopore in order to analyze the forces on the DNA. The results of the research were published on March 29 in Nature Physics. http://www.physorg.com/news161519158.html Nanotechnology Thu, 14 May 2009 11:26:30 EST news161519158 A semiconductor membrane designed by researchers at the University of Illinois could offer more flexibility and better electrical performance than biological membranes. Built from thin silicon layers doped with different impurities, the solid-state membrane also could be used in applications such as single-molecule detection, protein filtering and DNA sequencing. http://www.physorg.com/news103469529.html Nanotechnology Thu, 12 Jul 2007 14:32:09 EST news103469529 Using computer simulations, researchers at the University of Illinois have demonstrated a strategy for sequencing DNA by driving the molecule back and forth through a nanopore capacitor in a semiconductor chip. The technique could lead to a device that would read human genomes quickly and affordably. http://www.physorg.com/news116691000.html Nanotechnology Wed, 12 Dec 2007 14:10:00 EST news116691000 Resistive pulse sensing represents a very attractive method for identifying and quantifying biomedical species such as drugs, DNA, proteins, and viruses in solution. http://www.physorg.com/news105069582.html Nanotechnology Tue, 31 Jul 2007 02:59:42 EST news105069582 (PhysOrg.com) -- Boston University biomedical engineers have devised a method for making future genome sequencing faster and cheaper by dramatically reducing the amount of DNA required, thus eliminating the expensive, time-consuming and error-prone step of DNA amplification. http://www.physorg.com/news180531065.html Nanotechnology Sun, 20 Dec 2009 13:00:03 EST news180531065 Researchers at Purdue's Birck Nanotechnology Center have shown how "nanopore channels" can be used to rapidly and precisely detect specific sequences of DNA as a potential tool for genomic applications in medicine, environmental monitoring and homeland security. http://www.physorg.com/news95006759.html Nanotechnology Thu, 05 Apr 2007 15:45:59 EST news95006759 Nanopores, holes less than one-thousand the width of a human hair, are capable of isolating strands of DNA or therapeutic drugs from a solution, based mostly on the size of the pores. Now, a chemist at the University of Massachusetts Amherst has created nanopores that can recognize and interact with certain molecules, actively controlling their movement across synthetic membranes. Results were published online Feb. 3 in Nature Nanotechnology. http://www.physorg.com/news123179185.html Nanotechnology Mon, 25 Feb 2008 16:26:25 EST news123179185 A team led by physicists at the University of California, San Diego has shown the feasibility of a fast, inexpensive technique to sequence DNA as it passes through tiny pores. The advance brings personalized, genome-based medicine closer to reality. http://www.physorg.com/news63553078.html Nanotechnology Thu, 06 Apr 2006 14:37:58 EST news63553078 Imagine being able to rapidly identify tiny biological molecules such as DNA and toxins using a system that can fit on a microchip or in a drop of salt water. It`s closer than you might think, say a team of researchers from the National Institute of Standards and Technology, Brazil`s Universidade Federal de Pernambuco, and Wright State University in Dayton, Ohio. http://www.physorg.com/news98097633.html Nanotechnology Fri, 11 May 2007 10:20:33 EST news98097633 Since the human genome was sequenced six years ago, the cost of producing a high-quality genome sequence has dropped precipitously. More recently, the National Institutes of Health called for cutting the cost to $1,000 or less, which may enable sequencing as part of routine medical care. http://www.physorg.com/news159024506.html Nanotechnology Wed, 15 Apr 2009 14:28:50 EST news159024506 (PhysOrg.com) -- Using an RNA-powered nanomotor, University of Cincinnati (UC) biomedical engineering researchers have successfully developed an artificial pore able to transmit nanoscale material through a membrane. http://www.physorg.com/news173367207.html Nanotechnology Mon, 28 Sep 2009 14:33:52 EST news173367207 Sponges with pores only nanometers in diameter could help lead to advanced fuel cells in hydrogen-powered cars, as well as super-coolants to keep perishable drugs fresh and devices to clean out toxins in the body, experts told UPI's Nano World. http://www.physorg.com/news5208.html Nanotechnology Fri, 15 Jul 2005 08:27:41 EST news5208 In what should be good news for integrated circuit manufacturers, recent studies by the National Institute of Standards and Technology have helped resolve two important questions about an emerging microcircuit manufacturing technology called nanoimprint lithography -yes, it can accurately stamp delicate insulating structures on advanced microchips, and, no, it doesn`t damage them, in fact it makes them better. http://www.physorg.com/news128707959.html Nanotechnology Tue, 29 Apr 2008 17:12:39 EST news128707959
