"Integrating DNA strand-displacement circuitry with DNA tile self-assembly." <i>Nature Communications,</i> 4, (2013) Macmillan Publishers Limited: http://dx.doi.org/10.1038/ncomms2965.https://hdl.handle.net/1911/88317DNA nanotechnology has emerged as a reliable and programmable way of controlling matter at the nanoscale through the specificity of Watson–Crick base pairing, allowing both complex self-assembled structures with nanometer precision and complex reaction networks implementing digital and analog behaviors. Here we show how two well-developed frameworks, DNA tile self-assembly and DNA strand-displacement circuits, can be systematically integrated to provide programmable kinetic control of self-assembly. We demonstrate the triggered and catalytic isothermal self-assembly of DNA nanotubes over 10 μm long from precursor DNA double-crossover tiles activated by an upstream DNA catalyst network. Integrating more sophisticated control circuits and tile systems could enable precise spatial and temporal organization of dynamic molecular structures.engThis work is licensed under a Creative Commons Attribution-NonCommercial-NoDerivs 3.0 Unported License.Journal articlehttp://dx.doi.org/10.1038/ncomms2965
