microtubule–kinesin system is used to form microtubule-based
structures via microtubule gliding motility. On the kinesin-coated
surface, the microtubules can be easily assembled into stable micro-
and nanostructures like circles and microtubule bundles using the
streptavidin–biotin system. Furthermore, these microtubules
structures can still retain performance with kinesin motor movement
in spite of different velocities. Collisions bear responsibility for
the majority of events leading to circle formation. By taking advantage
of biological substances, some micro- or nanostructures, which are
difficult to fabricate by artificial processes, can be easily obtained.
