In recent years, metal nanoparticles have showed great application prospect in the field of biological imaging, cancer diagnosis and treatment due to its unique optical scattering and optical absorption properties. In many metal materials, gold nanoparticles have caused concerns in the field because of its simple preparation, easy to modify advantages. However, the poor stability in physiological fluids environment and the potential toxicity of gold nanoparticles always restricts its...

Stockholm, Apr 26, 2013 - (ACN Newswire) - Nanoparticles are currently used in commercial products ranging from catalysts, polishing media and magnetic fluids to cosmetics and sunscreens. A new review by researchers in Sweden and Spain describes recent work to optimize the synthesis, dispersion and surface functionalization of titania, zinc oxide and ceria - the three main nanoparticles used in photocatalytic, UV-blocking and sunscreen applications.With the commercial success of self-cleaning...

The macroscopic effects of certain nanoparticles on human health have long been clear to the naked eye. What scientists have lacked is the ability to see the detailed movements of individual particles that give rise to those effects. In a recently published study, scientists at the Virginia Tech Carilion Research Institute invented a technique for imaging nanoparticle dynamics with atomic resolution as these dynamics occur in a liquid environment. The results will allow, for the first...

New research from the University of Southampton has found that working or traveling on an underground railway for a sustained period of time could have health implications. Previously published work suggests that working in environments such as steel mills or welding plants, which are rich in airborne metals, like iron, copper and nickel, can have damaging effects on health. However, little research has been done on the effects of working in an underground railway environment — a...

In a new study performed at the Center for Nanoscale Materials at the U.S. Department of Energy´s (DOE) Argonne National Laboratory, researchers have for the first time seen the self-assembly of nanoparticle chains in situ, that is, in place as it occurs in real-time. The scientists exposed a tiny liquid “cell” or pouch that contained gold nanoparticles covered with a positively charged coating to an intense beam of electrons generated with a transmission electron...

Cuts in federal funding of nanotechnology research threaten to slow progress toward some of the field's greatest promises, including commercialization of sustainable new energy sources that do not contribute to global warming, an international authority in the field cautioned here today. Speaking at the 245th National Meeting & Exposition of the American Chemical Society, the world's largest scientific society, A. Paul Alivisatos, Ph.D., expressed concern that the cuts come when...
