Technology Improved To Detect Hazardous Chemicals
2012-11-21 11:11:49

Imperial College London Scientists at Imperial College London have developed a system to quickly detect trace amounts of chemicals like pollutants, explosives or illegal drugs. The new system can pick out a single target molecule from 10 000 trillion water molecules within milliseconds, by trapping it on a self-assembling single layer of gold nanoparticles. The team of scientists, all from the Department of Chemistry at Imperial, say this technology opens the way to develop devices...

'BRIGHTS' Reveal Location Of Targeted Tissues
2012-11-21 10:41:38

Washington University in St. Louis Called BRIGHTs, the tiny probes described in the online issue of Advanced Materials on Nov. 15, bind to biomarkers of disease and, when swept by an infrared laser, light up to reveal their location. Tiny as they are, the probes are exquisitely engineered objects: gold nanoparticles covered with molecules called Raman reporters, in turn covered by a thin shell of gold that spontaneously forms a dodecahedron. The Raman reporters are molecules whose...

In a world-first, researchers from the Australian Centre for Nanomedicine at the University of New South Wales (UNSW) in Sydney have developed a nanoparticle that could improve the effectiveness of chemotherapy for neuroblastoma by a factor of five. Neuroblastoma is an aggressive childhood cancer that often leaves survivors with lingering health problems due to the high doses of chemotherapy drugs required for treatment. Anything that can potentially reduce these doses is considered an...

New nanotechnology can be used for Type 1 diabetes, food allergies and asthma -New nanoparticle tricks and resets immune system in mice with MS -First MS approach that doesn't suppress immune system -Clinical trial for MS patients shows why nanoparticle is best option -Nanoparticle now being tested in Type 1 diabetes and asthma In a breakthrough for nanotechnology and multiple sclerosis, a biodegradable nanoparticle turns out to be the perfect vehicle to stealthily deliver an antigen...

Airborne Particles Smuggle Pollutants Worldwide
2012-11-15 19:32:38

DOE/Pacific Northwest National Laboratory Symbiotic relationship between pollutants and airborne particles explains how city pollution ends up in Arctic Pollution from fossil fuel burning and forest fires reaches all the way to the Arctic, even though it should decay long before it travels that far. Now, lab research can explain how pollution makes its lofty journey: rather than ride on the surface of airborne particles, pollutants snuggle inside, protected from the elements on the way....

Researchers Create Nano-Scale Laser
2012-11-06 14:03:23

Michael Harper for redOrbit.com — Your Universe Online It´s a familiar theme: As research and technology evolve, the components involved become more reliable, more advanced and, ultimately, smaller. The first computers, used mostly to churn through calculations, were housed in giant rooms. Now, we carry computers with the same amount of power in our pockets. The same can be said of lasers. What once took up a good amount of space on a table can now be carried around on a key...

No Assembly Required - Microparticles That Self-assemble
2012-10-31 15:46:47

Harvard University Scientists have created new kinds of particles, 1/100th the diameter of a human hair, that spontaneously assemble themselves into structures resembling molecules made from atoms. These new particles come together, or "self-assemble," to form structures in patterns that were previously impossible to make and hold promise for manufacturing advanced optical materials and ceramics. The method, described in the latest issue of the journal Nature, was developed by a team of...

How Can Ingesting Silver Turn Your Skin Blue
2012-10-31 04:28:31

April Flowers for redOrbit.com - Your Universe Online When is your skin like a black and white photograph? Sounds like the start to a bad riddle, right? Instead, it's the essential question behind a new study from Brown University. The study shows, for the first time, how ingesting too much silver can cause argyria, which is a rare condition that turns a patient's skin a striking shade of grayish blue. "It's the first conceptual model giving the whole picture of how one develops this...

Nano3D Biosciences announced today that it has signed a distribution agreement with MIDSCI, a scientific products distribution company based in St. Louis, MO to sell its BioAssembler product line. The BioAssembler is a revolutionary 3D cell culture technology that utilizes magnetic nanoparticles to create a scaffold-less 3D cell culture environment. Houston, TX (PRWEB) October 25, 2012 Nano3D Biosciences (n3D), a company that specializes in three dimensional (3D) cell culturing products for...

Lung Mucus Gel Prevents Nanoparticles From Getting Through
2012-10-23 10:54:10

Joint press release by the Saarland University and the Helmholtz Centre for Infection Research Mucus coats our airways' internal surfaces. The viscous gel humidifies the lungs and prevents viruses and other small particles like diesel soot from entering the body unchecked. Previously unclear was the extent to which such nanoparticles are able to move through the lungs' mucus. Here, the research evidence was contradictory. Scientists could not explain why, in inhaled medication development,...
