NIST reference materials are 'gold standard' for bio-nanotech research
The National Institute of Standards and Technology (NIST) has issued its first reference standards for nanoscale particles targeted for the biomedical research community-literally "gold standards" for labs studying the biological effects of nanoparticles.   view more (2008-01-10)

Colorful bacteria more dangerous
A new study in the July 18 issue of The Journal of Experimental Medicine shows that gold-colored bacteria are more harmful than their unpigmented relatives. A group of scientists led by Victor Nizet (UCSD, San Diego, CA) have discovered that the molecules that give certain bugs their color also... view more (2005-07-12)

Gold nanostars outshine the competition
Novel nanoparticles being tested at the National Institute of Standards and Technology (NIST) have researchers seeing stars. In a recent paper, NIST scientists used surface-enhanced Raman spectroscopy (SERS) to demonstrate that gold nanostars exhibit optical qualities that make them superior for... view more (2008-10-16)

Mystery solved: Gold's power against autoimmune diseases defined
Gold compounds have been used for the treatment of rheumatoid arthritis and other autoimmune diseases for more than 75 years, but until now, how the metals work has been a mystery.   view more (2006-02-27)

Gold-tipped nanocrystals developed by Hebrew University researchers
"Nanodumbells" - gold-tipped nanocrystals which can be used as highly-efficient building blocks for devices in the emerging nanotechnology revolution - have been developed by researchers at the Hebrew University of Jerusalem. The technology, developed by a research group headed by Prof.... view more (2004-06-17)

Road to greener chemistry paved with nano-gold, researchers report
The selective oxidation processes that are used to make compounds contained in agrochemicals, pharmaceuticals and other chemical products can be accomplished more cleanly and more efficiently with gold nanoparticle catalysts, researchers have reported in Nature magazine.   view more (2005-10-26)

Gold, copper nanoparticles take center stage in the search for hydrogen production catalysts
X-ray studies at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory are pointing the way to less costly and more efficient catalysts for improving the performance of fuel cells.   view more (2007-03-29)

Brookhaven lab scientists stabilize platinum electrocatalysts for use in fuel cells
Platinum is the most efficient electrocatalyst for accelerating chemical reactions in fuel cells for electric vehicles. In reactions during the stop-and-go driving of an electric car, however, the platinum dissolves, which reduces its efficiency as a catalyst. This is a major impediment for... view more (2007-01-15)

Direct photon properties reveal secrets of extreme nuclear states
When atomic nuclei are smashed together at great speed, resulting temperatures exceed one trillion degrees, 200 million times hotter than the surface of the sun.   view more (2006-04-26)

New protein synthesis not essential to memory formation
New research from the University of Illinois challenges the premise that the brain must build new proteins in response to an experience for that experience to be recorded in long-term memory.    view more (2007-07-27)

Purifying nanorods: Big success with tiny cleanup
Chemists at Rice University have discovered a novel method to produce ultra-pure gold nanorods -- tiny, wand-like nanoparticles that are being studied in dozens of labs worldwide for applications as broad as diagnosing disease and improving electronic viewscreens.   view more (2008-09-23)

Gold nanoparticles show potential for noninvasive cancer treatment
