DNA cages guide nanoparticle self-assembly

Abstract:
Trapping nanoparticles in cages made of DNA could finally allow them to self-assemble into transistors, metamaterials and even tiny robots. The technique should prevent the nanoparticles clumping together at random, one of the biggest problems with nanoscale self-assembly.

Now, Alexei Tkachenko and Nicolas Licata from the University of Michigan, Ann Arbor, have come up with a solution: trap the nanoparticles in a cage where the bars are made of DNA, and then stack the cages to form nanostructures.
