Magnetic atoms of gold, silver and copper have been obtained
An international team led by Physics and Chemistry teams from the Faculty of Science and Technology at the University of the Basque Country (UPV/EHU) and directed by Professor Jose Javier Saiz Garitaonandia, has achieved, by means of a controlled chemical process, that atoms of gold, silver and copper - intrinsically non-magnetic (not attracted to... view more...

Counting semi-viable bacteria in cheese
The Wageningen researcher Christine Bunthof has developed a direct method for counting bacteria in dairy products. The method not only distinguishes viable and non-viable bacteria but also semi-viable bacteria. These are too weak to divide, but still exhibit activity. The semi-viable bacteria play an important role in cheese ripening and therefore... view more... (2002-05-23)
Gold nanoparticles show potential for noninvasive cancer treatment
Researchers from the University of California, San Francisco and Georgia Institute of Technology have found a new way to kill cancer cells. Building on their previous work that used gold nanoparticles to detect cancer, they now are heating the particles and using them as agents to destroy malignant cells. view more (2005-10-10)
Using Life's Building Blocks to Control Nanoparticle Assembly
Using DNA, the molecule that carries life's genetic instructions, researchers at the U.S. Department of Energy's Brookhaven National Laboratory are studying how to control both the speed of nanoparticle assembly and the structure of its resulting nanoclusters. view more (2007-08-23)
Repetitive motion speeds nanoparticle uptake
Newly published research by Rice University chemists and North Carolina State University toxicologists finds that repetitive movement can speed the uptake of nanoparticles through the skin. view more (2007-01-05)
'Custom' nanoparticles could improve cancer diagnosis and treatment
Researchers have developed "custom" nanoparticles that show promise of providing a more targeted and effective delivery of anticancer drugs than conventional medications or any of the earlier attempts to fight cancer with nanoparticles. view more (2006-03-27)
MIT, Brigham: Nanoparticles armed to combat cancer
Ultra-small particles loaded with medicine-and aimed with the precision of a rifle-are offering a promising new way to strike at cancer, according to researchers working at MIT and Brigham and Women's Hospital. view more (2006-04-11)
Using Nanoparticles, In Vivo Gene Therapy Activates Brain Stem Cells
Using customized nanoparticles that they developed, University at Buffalo scientists have for the first time delivered genes into the brains of living mice with an efficiency that is similar to, or better than, viral vectors and with no observable toxic effect, according to a paper published this week in Proceedings of the National Academy of... view more...

Argonne scientists discover networks of metal nanoparticles are culprits in alloy corrosion
Oxide scales are supposed to protect alloys from extensive corrosion, but scientists at U.S. Department of Energy's Argonne National Laboratory have discovered metal nanoparticle chinks in this armor. view more (2008-08-05)
Magnetic nanoparticles to simultaneously diagnose, monitor and treat
Whether it's magnetic nanoparticles (mNPs) giving an army of 'therapeutically armed' white blood cells direction to invade a deadly tumour's territory, or the use of mNPs to target specific nerve channels and induce nerve-led behaviour (such as the life-dependant thumping of our hearts), mNPs have come a long way in the past decade. view more (2009-11-06)
Proofreading and error-correction in nanomaterials inspired by nature
Mimicking nature, a procedure developed by researchers at the University of Illinois at Urbana-Champaign can find and correct defects in self-assembled nanomaterials. view more (2005-10-19)
Researchers develop marker that identifies energy-producing centers in nerve cells
A protein that causes coral to glow is helping researchers at the University of Maryland School of Medicine to light up brain cells that are critical for the proper functioning of the central nervous system. view more (2007-02-02)
Beyond the hype and the scare stories, how safe are nanoparticles?
The May issue of Nano Today (www.nanotoday.com) launches a dedicated forum for debate on the effects of nanoparticles on human health. In "Nanotechnology: assessing the risks", Andrew Maynard of the Woodrow Wilson International Center for Scholars calls for a strategic approach to research on potential risks to ensure the development of... view more...

Silica smart bombs deliver knock-out to bacteria
Bacteria mutate for a living, evading antibiotic drugs while killing tens of thousands of people in the United States each year. view more (2008-02-26)
The UAB heads a European research project on proteases and pathological processes
A research group of the UAB Institute of Biotechnology and Biomedicine and the UAB Department of Biochemistry and Molecular Biology, directed by Francesc Xavier Avilés, is the coordinator of a European project aimed at studying proteases with fluorescent molecules that allow their monitoring in healthy and pathological situations. view more (2007-07-18)
Scorpion venom with nanoparticles slows spread of brain cancer
By combining nanoparticles with a scorpion venom compound already being investigated for treating brain cancer, University of Washington researchers found they could cut the spread of cancerous cells by 98 percent, compared to 45 percent for the scorpion venom alone. view more (2009-04-17)
Nanotechnology enables low-dose treatment of atherosclerotic plaques
In laboratory tests, one very low dose of a drug was enough to show an effect on notoriously tenacious artery-clogging plaques. What kind of drug is that potent? view more (2006-07-28)
Nanotechnologies Bring Great Potential And Need For Responsible Development
Nanotechnology offers many potential benefits, but its development must be guided by appropriate safety assessments and regulation to minimise any possible risks to people and the environment, according to a report published today (29 July 2004) by the Royal Society and the Royal Academy of Engineering. The report was commissioned by the UK... view more... (2004-07-29)
New technology shows promise against resistant staph infections
Scientists at Albert Einstein College of Medicine of Yeshiva University have combined their revolutionary new drug-delivery system with a powerful antimicrobial agent to treat potentially deadly drug-resistant staph infections in mice. view more (2009-05-01)
Nanoparticle created to attack cardiovascular plaque
Scientists and engineers at UC Santa Barbara and the Burnham Institute for Medical Research have developed a nanoparticle that can attack plaque-a major cause of cardiovascular disease. view more (2009-06-08)
