polydimethylsiloxane template
to construct polymer-based autonomous micromotors with various structures.
Solid or hollow micromotors, which consist of polycaprolactone and
platinum nanoparticles, can be obtained with controllable sizes and
shapes. The resulting micromotor can not only be self-propelled in
solution based on the bubble propulsion mechanism in the presence
of the hydrogen peroxide fuel, but also exhibit structure-dependent
motion behavior. In addition, the micromotors can exhibit various
functions, ranging from fluorescence, magnetic control to cargo transportation.
Since the current method can be extended to a variety of organic and
inorganic materials, we thus believe it may have great potential in
the fabrication of different functional micromotors for diverse applications.
