- Ingredient in Big Macs and sodas can stabilize
02-26-2007 · EurekAlert!
The potential of gold nanoparticles to detect and treat cancer has been hindered by the difficulty of making them in a stable, nontoxic form that can be injected into a patient. New research at the University of Missouri-Columbia has found that a plant extract can be used to overcome this problem, creating a new type of gold nanoparticle that is stable and nontoxic and can be administered orally or injected.

- New nanoparticle could provide simple early diagnosis of many diseases
08-20-2007 · EurekAlert!
Georgia Tech and Emory University researchers have created a new nanoparticle that could someday act as a virtually all-purpose diagnostic tool to detect many inflammatory diseases in their earliest stages, including heart disease, Alzheimer's, heart disease and arthritis. The specially-designed nanoparticles seek out hydrogen peroxide (thought to be overproduced in trace amounts in the early stages of most diseases that involve some sort of chronic inflammation in the body), and emit light when they encounter it.

- Pairing Nanoparticles with Proteins
06-27-2007 · Brookhaven National Laboratory
In groundbreaking research, scientists have demonstrated the ability to strategically attach gold nanoparticles - particles on the order of billionths of a meter - to proteins so as to form sheets of protein-gold arrays. The nanoparticles and methods to create nanoparticle-protein complexes can be used to help decipher protein structures, to identify functional parts of proteins, and to "glue" together new protein complexes.

- Bio-inspired assembly of nanoparticle building blocks
11-27-2006 · EurekAlert!
Rice University chemists have discovered how to assemble gold and silver nanoparticle building blocks into larger structures based on a novel method that harkens back to one of nature's oldest known chemical innovations -- the self-assembly of lipid membranes that surround all living cells. The research appears in the Nov. 29 issue of the Journal of the American Chemical Society. It could help scientists design everything from better catalysts to potent new anti-cancer drugs.

- NIST reference materials are 'gold standard' for bio-nanotech research
01-09-2008 · EurekAlert!
The National Institute of Standards and Technology 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. The three new materials, gold spheres nominally 10, 30 and 60 nanometers in diameter, were developed in cooperation with the National Cancer Institute's Nanotechnology Characterization Laboratory.
