Base Stacking Adhesive Forces versus OPTIMuS actuators: TEM analysis.

For each sample, a two-dimensional (2D) rendering was generated using corresponding caDNAno layout, followed by TEM imaging, extraction of three representative images and histrograms showing the density distribution of the overall length of OPTIMuS populations in various configurations. Red curve represents the Normal distribution, blue curve shows the actual distribution and the green dashed line indicates the average length of OPTIMuS in the corresponding pre-added force domain configuration (based on data acquired in Fig. 2). (a) TEM images of ground state containing all blunt ends in the presence of different force domains. (b) A schematic of the blunt end and non-blunt end interactions between the coaxial helices of ring and frame^R.
