a| A DNA origami Möbius was cut along its strips using SDR to
produce two interlocked rings (left). The atomic force microscopy (AFM) height
(right, top row), amplitude (right, middle row), and transmission electron
microscopy (TEM) (right, lower row) images of the products83. b| The left
origami frame was transformed to the middle and then the right frame using
staple subset removal by SDR and addition of a new subset of staples as
confirmed by the AFM (bottom row)84. c| AFM images of the SDR-mediated carved
letters of alphabet off a 2D molecular canvas assembled using single-stranded
DNA brick assembly technique85. Panels A-C were adapted from REFs. 83, 84, 85, respectively, with permissions from Springer Nature,
