Inspired by origami, North Carolina State University researchers have found a way to remotely control the order in which a 2D sheet folds itself into a 3D structure. “The sequence of folding is important in life as well as in technology,” says Genzer, the S. Frank and Doris Culberson Distinguished Professor of Chemical and Biomolecular Engin

eering at NC State. “On small length scales, sequential folding via molecular machinery enables DNA to pack efficiently into chromosomes and assists proteins to adopt a functional conformation. On large length scales, sequential folding via motors helps solar panels in satellites and space shuttles unfold in space...
