DNA on Autopilot

Techonology Networks | January 04, 2019

Nature has made extravagant use of a simple molecule--DNA, the floorplan of all earthly life. Inventive researchers have used the same base-pairing properties that bond two strands of DNA into the familiar double helix to build innumerable useful structures at the nanometer scale. One such method, known as DNA origami, has yielded rich results in recent years, enabling the construction of a rapidly growing menagerie of 2- and 3-dimensional objects, with far-flung applications in material science, nanoelectronics, photonics, and the biomedical arena. In new research appearing in the current issue of the journal Science Advances, Hao Yan and his colleagues, in collaboration with scientists at MIT, describe a method allowing for the automation of DNA origami construction, vastly accelerating and simplifying the process of crafting desired forms, and opening the world of DNA architecture to a broader audience. "DNA origami design has come to the time that we now can draw a form freely and ask the computer to output what is needed to build the target form," Yan says. The variety and versatility of DNA nanoarchitectures have enabled their application for tiny logic gates and nanocomputers, advanced materials with unique properties, nanoelectronics and nanocircuitries and structures displaying dynamic properties, including nanotweezers, nanowalkers, and nanorobots.
