    Description: Engineering wireframe architectures and scaffolds of increasing complexity is one of the important challenges in nanotechnology. We present a design strategy to create gridiron-like DNA structures. A series of four-arm junctions are used as vertices within a network of double-helical DNA fragments. Deliberate distortion of the junctions from their most relaxed conformations ensures that a scaffold strand can traverse through individual vertices in multiple directions. DNA gridirons were assembled, ranging from two-dimensional arrays with reconfigurability to multilayer and three-dimensional structures and curved objects.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Han, Dongran -- Pal, Suchetan -- Yang, Yang -- Jiang, Shuoxing -- Nangreave, Jeanette -- Liu, Yan -- Yan, Hao -- New York, N.Y. -- Science. 2013 Mar 22;339(6126):1412-5. doi: 10.1126/science.1232252.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉The Biodesign Institute, Arizona State University, Tempe, AZ 85287, USA. dongran.han@asu.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/23520107" target="_blank"〉PubMed〈/a〉
