Structural stability test against low salt denaturation. a) 32, 52, and 74 nt brick nanostructures and 3D origami were assembled at either 10 or 40 mm MgCl₂ (lanes 4, 7, 10, and 13). Assembled samples were incubated at 37 °C in 1×PBS for 1 hour, then spin‐filtered to completely remove any remaining salt in solution (lanes 5, 8, 11, and 14). All samples were characterized via agarose gel electrophoresis. b) TEM images were taken to confirm the preservation of structures. Scale bars indicate 50 nm in length.
