Abstract

We present a novel metal-ion stimulated organization of DNA origami nanostructures by employing G-quadruplexes as stimuli-responsive bridges. The reversible assembly process of DNA origami was the result of conformational changes between the G-quadruplex and its single-strand state induced by monovalent cations. This study might stimulate a new design of responsive DNA-based intelligent nanomaterials.
