Study shows quantum dots can penetrate skin through minor abrasions

Researchers at North Carolina State University have found that quantum dot nanoparticles can penetrate the skin if there is an abrasion, providing insight into potential workplace concerns for healthcare workers or individuals involved in the manufacturing of quantum dots or doing research on potential biomedical applications of the tiny nanoparticles.

Super atoms turn the periodic table upside down

Researchers at Delft University of Technology in The Netherlands have developed a technique for generating atom clusters made from silver and other metals. Surprisingly enough, these so-called super atoms (clusters of 13 silver atoms, for example) behave in the same way as individual atoms and have opened up a whole new branch of chemistry.

Trade Unions call for REACH amendment to cover nanomaterials

European labour unions have called on the European Commission to amend the REACH regulation on chemicals to better protect workers against nanomaterials throughout their lifecycle. Their call comes shortly after the EU executive argued that nanotechnology is already covered by existing EU regulation.

Gold, DNA combination may lead to nano-sensor

A team of Duke University materials engineers and chemists has developed tiny gold nanostructures that can create signals from subtle changes in light reflecting off their nanoscale surfaces. The sub-cellular size of the nanostructures and their ability to absorb or scatter light as their structure changes makes them appealing as biological sensors, the researchers said.

More evidence for a revolutionary theory of water

The traditional picture of how liquid water behaves on a molecular level is wrong, according to new experimental evidence collected by a collaboration of researchers from the Department of Energy's Stanford Linear Accelerator Center (SLAC) in California, RIKEN SPring-8 synchrotron and Hiroshima University in Japan and Stockholm University in Sweden.
