Abstract
Tadpole-like Janus nanotubes with controlled size are fabricated by a sol–gel reaction at the emulsion interface. Pd or Fe3O4 nanoparticles can be selectively captured into their cavities to obtain tadpole-like Janus Pd-nanotubes or tadpole-like Janus Fe3O4-nanotubes. They can be driven directionally by a chemical fuel or near-infrared (NIR) light.
