Abstract
The electrical characteristics of single rectangular DNA origami structures are explored by trapping them via dielectrophoresis between nanoelectrodes (see image) and determining their conductivity mechanisms by AC impedance spectroscopy, combined with a detailed equivalent‐circuit model. The results show that the nature of the DNA origami conductivity is not purely Ohmic but that it is a combination of an ionic diffusion and electronic conductivity.
