Components for actuated assemblies. The prototype nanomachines include a a nano-rotor composed of two separate constructs, the nano-brick and a nano platform, which are connected together via single-stranded DNA (ssDNA) overhang and b nano-hinge consisting of two stiff nano-rods with 36 double-stranded DNA (dsDNA) helices joined at one end by 8 ssDNA strand connections. c A 56-helix nano-brick composed of 56 dsDNA helices bundled together was used as a basis for a lever arm. d The DNA mechanical lever arm for actuation is a 1D array of nano-bricks. Cylindrical models are shown for each with each cylinder representing a DNA helix. AFM and TEM images are shown with scale bar 50 nm for images ac and 500 nm for image d
