Shrunk DNA origami

 First, We constructed shrunk DNA origami and the result is shown in Fig. 7 (a). As you can see, shrunk DNA origami was successfully constructed. Most Origamis are shrunk by 9 nm as compared to original DNA origami (Fig. 7 (b)) by blunt-end π–π stacking interactions within a molecule.

Cyclops and Smiley DNA origami

 Second, we prepared cyclops DNA Origami. Cyclops DNA Origami is not using staple strands in middle of Smiley DNA origami. We shown Fig. 8 to the result of AFM observation. This result show that the one-eyed smiley “Cyclops” was prepared. As expected, smiley DNA Origami was shrunk by blunt-end π–π stacking interactions within a molecule. Farther, we added staple strands of middle of Smiley DNA origami. In the result, cyclops DNA origami transformed the smiley DNA origami (Fig. 9).

Bear Trap DNA origami

 Third, we prepared DNA origami having a capability of shape selective capturing “Bear Trap”. We shown Fig.?? to the result of AFM observation. This result suggest that the architecture was formed Origami with the square hole in the center by π- π stacking interaction. We prepared plus shaped DNA origami for allow it to Bear Trap. The result showed string of plus shaped Origami. The next time, We mixed Bear Trap with plus shaped DNA origami. Against the odds, plus shaped DNA origami was not captured Bear Trap. Because we thought that Bear Trap's π- π stacking interaction is too strong.
