Fig. 2. Dynamic control of origami structures. (a) Schematic of structural changes in origami-1, TEM images and characteristic nanopore signals (more signals are shown in Fig. S4–S6†) when only one pair of the complementary strands (H1, H2) was introduced to produce origami-2. When three pairs of the complementary strands (H1⋯H6) were introduced, origami-1 became origami-3. Scale bar: 200 nm. (b) 1% agarose gel results for the three origamis. The red arrow is the origami structures that was formed.
