Assembly of systems. a ssDNA connecting two structures (polymerization strands) were designed with a u-shaped motif where half have a higher affinity to attach to one side of the interface while the other half have higher affinity to the other side of the interface. b Stiff micro levers are assembled by attaching 56 helix nano-bricks end-to-end using polymerization strands. AFM and TEM images show micro-levers. Scale bar is 1 μm. c The nano-rotor is assembled by attaching a nano-platform to a nano-brick via a single ssDNA overhang. AFM and TEM images show the nano-rotor construct. Scale bar is 50 nm. d Stiff micro-levers are formed off the arm of the nano-rotor using polymerization stands to connect the nano-arm to micro levers. AFM and TEM images show the assembled micro-rotor. Scale bar is 100 nm. e A single nano-brick is attached initially to the top and bottom of the nano-hinge using two separate sets of polymerization strands for top (green-blue) and bottom (red-blue). AFM and TEM images show the hinge with top and bottom nano-bricks attached. Scale bar is 50 nm. f Stiff micro-levers are formed off the initial nano-bricks by attaching top nano-rods (green) and bottom nano-rods (red) using two separate sets of polymerization staples for the top (green) and the bottom (red). Zoomed out image of AFM and TEM image show a polymerized nano-hinge (scale bars are 500 nm, left and right). Zoomed in image of the nano-hinge from in the AFM image (scale bar is 50 nm, middle)
