Abstract:
New processes that allow nanoparticles to assemble themselves into designer materials could solve some of today's technology challenges, Alex Travesset of Iowa State University and the Ames Laboratory reports in the Oct. 14 issue of the journal Science.

Physicist Says Nanoparticle Assembly Is Like Building with LEGOs

Ames, IA | Posted on October 14th, 2011

Travesset, an associate professor of physics and astronomy and an associate of the U.S. Department of Energy's Ames Laboratory, writes in the journal's Perspectives section that the controlled self-assembly of nanoparticles could help researchers create new materials with unique electrical, optical, mechanical or transport properties.

"Nanoparticle self-assembly has entered the LEGO era," Travesset said. "You can really work with nanoparticles in the same way you can work with LEGOs. This represents a breakthrough in the way we can manipulate matter. Really revolutionary applications will come."

In his commentary, Travesset reports on the ramifications of a scientific paper also published in the Oct. 14 issue of Science. Lead authors of the scientific paper are Chad Mirkin, director of the International Institute for Nanotechnology at Northwestern University in Evanston, Ill., and George Schatz, a professor of chemistry at Northwestern. Their research team describes new technologies that use complementary DNA strands to link nanoparticles and control how the particles precisely assemble into target structures.

Nanoparticles are so small - just billionths of a meter - that it is practically impossible to assemble real materials particle by particle. Past attempts to induce their self-assembly have been successful in only a handful of systems and in very restrictive conditions.

The developments by the Mirkin and Schatz research team are "likely to elevate DNA-programmed self-assembly into a technique for the design of nanoparticle structures a la carte," Travesset wrote.

Travesset's research program includes theoretical studies of the assembly of nanoparticles and how they can be uniformly mixed with polymers. A research paper describing some of his findings was published in the May 27 issue of the journal Physical Review Letters (Dynamics and Statics of DNA-Programmable Nanoparticle Self-Assembly and Crystallization).

With the development of efficient self-assembly technologies, Travesset said there's tremendous potential for nanoparticle science.

"Being able to assemble nanoparticles with such control represents a major accomplishment in our quest to manipulate matter," he wrote in Science. "There are immediate important applications related to catalysis, medical sensing, new optical materials or metamaterials, and others that will follow from these studies.

"Most likely, however, many other applications will arise as we dig deeper, understand better, expand further, and tinker with the opportunities provided by these materials."
