Nano monorail for molecular motors: Individually manipulated microtubules for kinesin motion

In a motor protein system (kinesin/microtubule), individual microtubules were captured and relocated to build a complex nano-scale transport system. Micro tweezers, attached to a micromanipulator arm, were used to capture polarity marked microtubules. Precise relocation of those microtubules provided an oriented track along which kinesin-coated beads move according to the microtubule polarities.
