Cylinder confinement used as a self assembly technique for nanoparticles


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.
