We show DNA origami nanopores that respond to high voltages by a change in conformation on glass nanocapillaries. Our DNA origami nanopores are voltage sensitive as two distinct states are found as a function of the applied voltage. We suggest that the origin of these states is a mechanical distortion of the DNA origami. A simple model predicts the voltage dependence of the structural change. We show that our responsive DNA origami nanopores can be used to lower the frequency of DNA translocation by I order of magnitude.
