The DNA molecule serves as the code of life, but it also serves as handy building material for nanoscale structures — and newly published research shows how patterns as complex as letters, numbers and smiley faces can be created far more cheaply and quickly than previously thought. Peng Yin, HMS assistant professor of systems biology and also a core faculty member at the Wyss Institute for Biologically Inspired Engineering, led the research with Bryan Wei, a postdoctoral fellow and Mingjie Dai, a graduate student.
