Nanoparticle Assembly is like Building With Legos
"ScienceDaily (2011-10-13) -- Scientists report that nanotechnology has entered a new era. Because of 
developments in nanoparticle self-assembly, designer materials with unique properties are now possible. And that could lead to immediate applications in catalysis, medical sensing and optics."
"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"
