Abstract

Researchers headed by William M. Shih of Boston's Dana-Faber Cancer Institute were able to use DNA as a basic chemical building block for building complex three dimensional nanostructures with precise dimensions. The structures are made by 'carving' them out of a honeycomb lattice made of a DNA double helix.
