The gold standard: Biodesign Institute researchers use nanoparticles to make 3-D DNA nanotubes
piggy submitted, created time 5 days 15 hours (www.eurekalert.org)
Arizona State University researchers Hao Yan and Yan Liu imagine and assemble intricate structures on a scale almost unfathomably small. Their medium is the double-helical DNA molecule, a versatile building material offering near limitless construction potential.
In the January 2, 2009 issue of Science, Yan and Liu, researchers at ASU's Biodesign Institute and faculty in the Department of Chemistry and Biochemistry, reveal for the first time the three-dimensional character of DNA nanotubules, rings and spirals, each a few hundred thousandths the diameter of a human hair 
Nanotechnology may pose health risks
Darkfrog submitted, created time 4 weeks 5 hours (www.nytimes.com)
When radium was first discovered, no one thought it was dangerous. People painted it onto the hands of clocks to make them glow in the dark. Shoe stores used to have X-ray machines that people could use to see the bones in their feet. Roofers used to install asbestos shingles. Now, nanotechnology are the next big thing, and new research from Scotland is suggesting that carbon nanotubes may be as dangerous as asbestos.
Clothing With a Brain: Smart Fabrics Monitor Health
piggy submitted, created time 4 weeks 18 hours (www.sciencedaily.com)
Researchers in United States and China are reporting progress toward a simple, low-cost method to make "smart fabrics," electronic textiles capable of detecting diseases, monitoring heart rates, and other vital signs. A report on these straight-out-of-science-fiction-fibers, made of carbon nanotubes, is scheduled for the December 10 issue of ACS' Nano Letters.
In the new study, Nicholas A. Kotov, Chuanlai Xu, and colleagues point out that electronic textiles, or E-textiles, already are a reality. However, the current materials are too bulky, rigid, and complex for practical use
New nano device detects immune system cell signaling
sea-maid submitted, created time 4 months 4 days (esciencenews.com)
Scientists have detected previously unnoticed chemical signals that individual cells use to communicate with each other over short distances. Minding the communiques of individual cells might not be so important for studying the heart or bones, but it is absolutely crucial to studying the immune system.
Flexible polymers make stretchy conductors
Darkfrog submitted, created time 4 months 3 weeks (sciencenow.sciencemag.org)
Scientists have managed to combine polymers and nanotubules to create a condictive surface that can be stretched up to 38% without loss of function. Just the thing for flexible circuit boards!
Now my question is what are we going to use this stuff for first? Oh sure, we could invent a blood sugar monitoring system that could fit right into a diabetic's vein, vital sign monitors that could be worn like a sweater vest, but I think it's far more likely that we end up with MP3 players that can be molded straight to the user's auditory canal
Nanotechnology Innovation May Revolutionize Gene Detection in a Single Cell
Eric wu submitted, created time 11 months 3 weeks (www.sciencedaily.com)
Scientists at Arizona State University's Biodesign Institute have developed the world's first gene detection platform made up entirely from self-assembled DNA nanostructures. The results, appearing in the January 11 issue of the journal Science, could have broad implications for gene chip technology and may also revolutionize the way in which gene expression is analyzed in a single cell.
Researchers Use Magnetic Fields, Rather Than Drugs, to Control Cellular Signaling
Eric wu submitted, created time 11 months 4 weeks (www.sciencedaily.com)
Researchers at Children's Hospital Boston have developed a new "nanobiotechnology" that enables magnetic control of events at the cellular level. They describe the technology, which could lead to finely-tuned but noninvasive treatments for disease, in the January issue of Nature Nanotechnology (published online January 3).

Fusing nanotechnology with cell biology to battle the ‘superbug’
jane2007 submitted, created time 1 year 1 month (www.topnews.in)
Nanotechnology scientists at the University of Idaho start ed a new project with a view to integrating nanonmaterials research with cell biology and bioscience research. He said that his team was trying to harness nanowires and other nanomaterials to hijack the methods bacteria use for toxin delivery, and to deliver drug therapies specifically to infected cells.

Nanotechnology requires immediate changes in EPA
Luneetty submitted, created time 1 year 7 months (www.eurekalert.org)
New nanomaterials and nanotechnology products are entering the market each week, and an adequate oversight system is necessary to identify and minimize any adverse effects of nano materials and products on health or the environment. Davies' report sets out an agenda for creating an effective oversight system as nanotechnology advances the technology that some have hailed as "the next industrial revolution."
Iowa State scientists demonstrate first use of nanotechnology to enter plant cells
claudia submitted, created time 1 year 7 months (www.iastate.edu)
A team of Iowa State University plant scientists and materials chemists have successfully used nanotechnology to penetrate plant cell walls and simultaneously deliver a gene and a chemical that triggers its expression with controlled precision. Their breakthrough brings nanotechnology to plant biology and agricultural biotechnology, creating a powerful new tool for targeted delivery into plant cells.
Nanotechnology provides 'green' path to environmentally sustainable economy
BIOBOSS submitted, created time 1 year 8 months (www.eurekalert.org)
As products made with nanometer-scale materials and devices spread to more industries and markets, there is a growing opportunity and responsibility to leverage nanotechnology to reduce pollution, conserve resources and, ultimately, build a "clean" economy, advises a new report from the Project on Emerging Nanotechnologies.
New nanocomposites may mean more durable tooth fillings
BIOBOSS submitted, created time 1 year 8 months (www.eurekalert.org)
Scientists at the American Dental Association's Paffenbarger Research Center, a joint research program at NIST, have shown that nanotechnology has the potential to lessen that toll by producing tooth restorations that are both stronger than any decay-fighting fillings available today, and more effective at preventing secondary decay.
Nanotechnological applications in medicine
athena submitted, created time 1 year 9 months (www.sciencedirect.com)
"Nanotechnology-based tools and techniques are rapidly emerging in the fields of medical imaging and targeted drug delivery. Employing constructs such as dendrimers, liposomes, nanoshells, nanotubes, emulsions and quantum dots, these advances lead toward the concept of personalized medicine and the potential for very early, even pre-symptomatic, diagnoses coupled with highly-effective targeted therapy. Highlighting clinically available and preclinical applications, this review explores the opportunities and issues surrounding nanomedicine."
