News From the Field
Oh, My Stars and Hexagons! DNA Code Shapes Gold Nanoparticles

August 8, 2012

gold circles, stars and hexagons DNA holds the genetic code for all sorts of biological molecules and traits. But University of Illinois researchers have found that DNA's code can similarly shape metallic structures. The team found that DNA segments can direct the shape of gold nanoparticles--tiny gold crystals that have many applications in medicine, electronics and catalysis. Each of the four DNA bases codes for a different gold particle shape: Rough round particles, stars, flat round discs and hexagons. Full Story

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) 2014, its budget is $7.2 billion. NSF funds reach all 50 states through grants to nearly 2,000 colleges, universities and other institutions. Each year, NSF receives about 50,000 competitive requests for funding, and makes about 11,500 new funding awards. NSF also awards about $593 million in professional and service contracts yearly.
