Gold Nanoparticles Help Detect a Toxic Metal--Mercury
April 27, 2007
With gold nanoparticles, DNA and 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 rivers, streams, lakes and oceans, to evaluate their safety as food and drinking water sources. An article detailing the technology's success will be published online April 27 by Angewandte Chemie, the prestigious European journal of applied chemistry.
The National Science Foundation (NSF) is an independent federal agency that supports fundamental research and education across all fields of science and engineering. In fiscal year (FY) 2016, its budget is $7.5 billion. NSF funds reach all 50 states through grants to nearly 2,000 colleges, universities and other institutions. Each year, NSF receives more than 48,000 competitive proposals for funding and makes about 12,000 new funding awards. NSF also awards about $626 million in professional and service contracts yearly.
