DNA Structures Coordinate Nanoparticle Self-Assembly
The aim of nanoparticle self-assembly research has been to get the particles to organize themselves into structures that are largely controlled by us. However, the level of control we have sought has sometimes left a little bit to be desired.
Now, researchers at the U.S. Department of Energy's (DOE’s) Brookhaven National Laboratory have demonstrated that polyhedral structures made from DNA can serve as a framework for ensuring that the nanoparticles self-assemble in the exact arrangement their minders intended. In these DNA structures, the nanoparticles can be assembled into crystalline and open 3-D frameworks that themselves can be interconnected, making possible a wide variety of different structures.
