Oh, My Stars and Hexagons! DNA Code Shapes Gold Nanoparticles
August 8, 2012
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.

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.
