Cylinder confinement used as a self assembly technique for nanoparticles

Logo-Nanoletters

Researchers at UC Berkeley and Lawrence Berkeley National Laboratory have used Hummingbird Scientific’s Tomography holder to demonstrate the new assembly technique, “cylindrical confinement” for 3D self-assemblies of nanoparticles. The results have been published in Nano Letters.

Direct assembly of nanosized building blocks into a functional entity has been a great challenge, especially for DNA templating which requires aqueous solution. Here , the researchers 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.
