Actuation of prototype nanomachines. a Actuation of nano-rotor. Fluorescence images of nano-rotor magnetically actuated in a flow channel via the micro-lever arm attached to micro-magnetic beads. The nano-platform is falsely colored in blue and arms in red with overlapping positions in white. The nano-rotor is rotated by 360 degrees with a frequency of 1 Hz and rotates by 90° every fourth of a second corresponding to video time frames at 0, 0.25, 0.5, 0.75 and 1 s. b Actuation of nano-hinge. Fluorescence images of nano-hinge magnetically opened and closed in a flow channel using the extension of micro-lever arms attached to micro-magnetic beads. The nano-hinge is falsely colored in blue and arms in red with overlapping positions in white. Video time shots of the hinge closing (0, 0.2, 0.4 s) and reopening (2, 2.2 s) such that the hinge was left closed from 0.4–1.8 s before being reopened. Scale bars are 1 μm
