Query: DNA-assembled nanoarchitectures with multiple components in regulated
  and coordinated motion   Coordinating functional parts to operate in concert is essential for
machinery. In gear trains, meshed gears are compactly interlocked, working
together to impose rotation or translation. In photosynthetic systems, a
variety of biological entities in the thylakoid membrane interact with each
other, converting light energy into chemical energy. However, coordinating
individual parts to carry out regulated and coordinated motion within an
artificial nanoarchitecture poses challenges, owing to the requisite control on
the nanoscale. Here, we demonstrate DNA-directed nanosystems, which comprise
hierarchically-assembled DNA origami filaments, fluorophores, and gold
nanocrystals. These individual building blocks can execute independent,
synchronous, or joint motion upon external inputs. These are optically
monitored in situ using fluorescence spectroscopy, taking advantage of the
sensitive distance-dependent interactions between the gold nanocrystals and
fluorophores positioned on the DNA origami. Our work leverages the complexity
of DNA-based artificial nanosystems with tailored dynamic functionality,
representing a viable route towards technomimetic nanomachinery.
