Query: Dynamic Actuation of DNA-Assembled Plasmonic Nanostructures in
  Microfluidic Cell-Sized Compartments   Molecular motor proteins form the basis of cellular dynamics. Recently,
notable efforts have led to the creation of their DNA-based mimics, which can
carry out complex nanoscale motion. However, such functional analogues have not
yet been integrated or operated inside synthetic cells toward the goal of
realizing artificial biological systems entirely from the bottom-up. In this
Letter, we encapsulate and actuate DNA-assembled dynamic nanostructures inside
cell-sized microfluidic compartments. These encapsulated DNA nanostructures not
only exhibit structural reconfigurability owing to their pH-sensitive molecular
switches upon external stimuli but also possess optical feedback enabled by the
integrated plasmonic probes. In particular, we demonstrate the power of
microfluidic compartmentalization for achieving on-chip plasmonic enantiomer
separation and substrate filtration. Our work exemplifies that the two unique
tools, droplet-based microfluidics and DNA technology, offering high precision
on the microscale and nanoscale, respectively, can be brought together to
greatly enrich the complexity and diversity of functional synthetic systems.
