DNA design that anyone can do
Researchers at MIT and Arizona State University have designed a computer program that allows users to translate any free-form drawing into a two-dimensional, nanoscale structure made of DNA. Until now, designing such structures has required technical expertise that puts the process out of reach of most people. Using the new program, anyone can create a DNA nanostructure of any shape, for applications in cell biology, photonics, and quantum sensing and computing, among many others. “What this work does is allow anyone to draw literally any 2-D shape and convert it into DNA origami automatically,” says Mark Bathe, an associate professor of biological engineering at MIT and the senior author of the study. The researchers published their findings in the Jan. 4 issue of Science Advances, and the program, called PERDIX, is available online. The lead authors of the paper are Hyungmin Jun, an MIT postdoc, and Fei Zhang, an assistant research professor at...
