All-in-one nanoparticle: A Swiss Army knife for nanomedicine
Nanoparticles are being developed to perform a wide range of medical uses -- imaging tumors, carrying drugs, delivering pulses of heat. Rather than settling for just one of these, researchers at the University of Washington have combined two nanoparticles in one tiny package. view more (2009-07-28)
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...

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 help them resist attack by immune cells called... view more...

U of T team heats up gold to surprising effect: it gets harder not softer
Common sense tells us that when you heat something up it gets softer, but a team of researchers, led by University of Toronto chemistry and physics professor R.J. Dwayne Miller, has demonstrated the exact opposite. view more (2009-01-23)
Platinum nanocatalyst could aid drugmakers
Nanoparticles combining platinum and gold act as superefficient catalysts, but chemists have struggled to create them in an industrially useful form. view more (2009-09-01)
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 chemical and biological sensing and imaging. 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)
A pain in the neck
The world record for fastest text message typing is held by a 21-year old college student from Utah, but his dexterous digits could mean serious injury later on. view more (2009-11-11)
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. Uri Banin of the Department of Physical Chemistry... view more... (2004-06-17)
Hollow gold nanospheres show promise for biomedical and other applications
A new metal nanostructure developed by researchers at the University of California, Santa Cruz, has already shown promise in cancer therapy studies and could be used for chemical and biological sensors and other applications as well. view more (2009-03-23)
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 vehicle-application of fuel cells. view more (2007-01-15)
Special gold nanoparticles show promise for 'cooking' cancer cells
Researchers are describing a long-awaited advance toward applying the marvels of nanotechnology in the battle against cancer. They have developed the first hollow gold nanospheres - smaller than the finest flecks of dust - that search out and "cook" cancer cells. view more (2009-03-23)
Gold Nanorods May Make Safer Cancer Treatment
Researchers at the Georgia Institute of Technology and the University of California, San Francisco, have found an even more effective and safer way to detect and kill cancer cells. view more (2006-03-14)
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
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)
