Abstract
The unique folding and assembling properties of DNA have been elaborated to construct various nanomachines that can be reversibly switched between two or more distinct conformations. For better applications and developments of DNA nanomachines, their responding outputs and sequence-selectivity need to be improved. Here we show that a simple addition of a cationic comb-type copolymer, poly(L-lysine)-graft-dextran, produces robust and quick responses of DNA-fueled nanomachines under moderate conditions including physiologically relevant conditions through hybrid stabilization and DNA strand exchange acceleration.
