NANOTECHNOLOGY UPDATE: Cotranscriptional folding of single RNA strand added to nanotechnology toolkit. “Since genetic information and the catalysis of chemical reactions are the two most basic functions of the molecular machinery of life, it is of considerable interest to explore what role RNA nanotechnology could play in developing the artificial molecular machine systems that will lead both to near term advances in various areas of nanotechnology and to the ultimate development of high-throughput atomically precise manufacturing (APM). Structural DNA nanotechnology predates RNA nanotechnology by a decade or more, and one of the key developments in building more complex nanostructures and devices from DNA has been DNA origami. So, what might we expect from last summer’s introduction of RNA origami?”
