Scientists believe that tiny DNA-based Robots and other nanodevices will be used to deliver medicine inside our bodies, detect the presence of deadly pathogens, and help manufacture increasingly smaller electronics. This was published in the journal Nature Materials. Researchers from Ohio State University which is led by former engineering doctoral student Chao-Min Huang unveiled new software they call MagicDNA.
Researchers developed a new tool that can design complex DNA based Robots and nanodevices than were ever possible before in a fraction of the time. This software helps to design ways to take tiny strands of DNA and combine them into complex structures with parts like rotors and hinges that can move and complete a variety of tasks, including drug delivery.
Carlos Castro, co-author of the study and associate professor of mechanical and aerospace engineering at Ohio State said that Researchers are working for this by doing this for several years with slower tools with tedious manual steps. These nanodevices that may have taken us several days to design before now take a few minutes.
In “bottom-up” design, researchers take single strands of DNA and decide how to organize them into the pattern they want, which allows fine control over local device structure and properties. Using the top-down approach they decide how their device needs to be shaped geometrically and then automate how the DNA strands are put together.
