Tiny electronically active chemicals can be made to form ordered layers on a surface, thanks to research supported by the European Science Foundation (ESF) through the EUROCORES program SONS 2 (Self-Organised NanoStructures).
A workshop on September 10-11, 2008 in Washington, DC brings together experts from diverse disciplines to evaluate how the field of risk analysis can address the considerable uncertainties currently associated with impacts from nanoscale materials and nanotechnologies.
Researchers from the U.S. Department of Energy's (DOE) Brookhaven National Laboratory and Stony Brook University have developed a new instrument that allows them to control the size of nanoclusters - groups of 10 to 100 atoms - with atomic precision.
Dr. Gino DiLabio, Research Council Officer at Canada's National Institute for Nanotechnology (NINT) in Edmonton, Alberta, has been awarded the 2008 Journal of Physical Organic Chemistry Award for Early Excellence in the Field of Physical Organic Chemistry.
Terrace-like elevations of just a few nanometres can form during production of organic thin films made from electrically conductive material. This phenomenon was previously only known from inorganic materials and is crucially important for future production of a new generation of semi-conductor components based on organic thin films.
Combining a nanoparticle with manganese, a metal that boosts magnetic resonance imaging signals, and an antibody that targets blood vessels, researchers have created a new type of imaging agent that also has the potential to deliver drugs to tumors.
More than 15 years ago, scientists discovered a way to stop a particular gene in its tracks. The Nobel Prize-winning finding holds tantalizing promise for medical science, but so far it has been difficult to apply the technique, known as RNA interference, in living cells.
Now scientists have succeeded in using quantum dots to address this problem.
A new treatment strategy using targeted nanoparticles to block metastasis with anti-cancer drugs leads to good results using significantly lower doses of toxic chemotherapy, with less collateral damage to surrounding tissue.
