Preparation and characterization
of Janus stomatocyte-based supramolecular
nanomotors (motor 1: Janus stomatocytes) and their NIR triggered motion.
(A) Schematic illustration of the construction of Janus stomatocytes
via dialysis treatment. (B) SEM image of a Janus polymersome before
dialysis, scale bar = 200 nm. (C) SEM image of a Janus stomatocyte
after dialysis, scale bar = 200 nm. (D) TEM image of a Janus stomatocyte,
scale bar = 200 nm. (E) Schematic depiction of the orientation of
Janus stomatocytes for energy-dispersive X-ray spectroscopy (EDX)
elemental mapping analysis. (F) Elemental mapping of Janus stomatocytes
by EDX showing the Janus morphology of stomatocytes. From left to
right: electron image, EDX mapping image of Au, and merged image.
Scale bar = 500 nm. (G) Velocity dependence of the Janus stomatocytes
on the NIR output laser power. (H) Mean square displacement (MSD)
of Janus stomatocytes versus time interval (Δt) analyzed from motion tracking trajectories.
