title: A lock-and-key mechanism for the controllable fabrication of DNA origami structures.
abstract: Controllable fabrication of DNA origami structures was achieved using cationic comb-type copolymers (CCCs) as locks and polyvinyl sulphonic acid (PVS) as a key. A CCC binds to the phosphate backbone of either M13mp18/staples alone or both together and restricts origami folding, while PVS unlocks the CCC, restoring the formation of origami structures.
