Biomolecular motors such as
F1-adenosine triphosphate synthase (F1-ATPase)
and myosin are similar in size, and they generate forces compatible
with currently producible nanoengineered structures. We have engineered
individual biomolecular motors and nanoscale inorganic systems,
and we describe their integration in a hybrid nanomechanical device
powered by a biomolecular motor. The device consisted of three
components: an engineered substrate, an F1-ATPase biomolecular motor, and fabricated nanopropellers. Rotation of the
nanopropeller was initiated with 2 mM adenosine triphosphate and
inhibited by sodium azide.
