Gold nanoparticles are everywhere. They are used in cancer treatments, automobile sensors, cell phones, blood sugar monitors and hydrogen gas production. However, until recently, scientists couldn't create the nanoparticles without producing synthetic chemicals that had negative impacts on the environment.

In 2002, U.S. farmers harvested 2.7 billion bushels of soybeans. Last year in Missouri, farmers harvested 194 million bushels of soybeans worth about $1.2 billion. Now, a team of researchers at the University of Missouri-Columbia is turning those soybeans into gold, with nothing more than a little water.

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.

Gold nanoparticles help detect a toxic metal -mercury

With gold nanoparticles, DNA and some smart chemistry as their tools, scientists at Northwestern University have developed a simple "litmus test" for mercury that eventually could be used for on-the-spot environmental monitoring of bodies of water, such as rivers, streams, lakes and oceans, to evaluate their safety as food and drinking water sources.
