Cylindrical confinement used as a self assembly technique for nanoparticles

Direct assembly of nanosized building blocks into a functional entity has been a great challenge, especially for DNA templating, which requires aqueous solution. Here, researchers from the University of California, Berkeley and Lawrence Berkeley National Lab were able to use Hummingbird Scientific’s Tomography holder to  observe 3D cylindrical confinement of nanoparticles and their self-assemblies into stacked rings and single and double helices.
