Using bundled strands of DNA to build Tinkertoy-like tetrahedral cages,scientists at the U.
S. Department of Energy's Brookhaven National Laboratory have devised a way to trap and arrange nanoparticles in a way that mimics the crystalline structure of diamond. The achievement of this complex yet elegant arrangement, as described in a paper published February 5, and 2016,in Science, may open a path to current materials that lift advantage of the optical and mechanical properties of this crystalline structure for applications such as optical transistors, and color-changing materials,and lightweight yet tough materials.
