A design methodology is reported to fabricate functional compound micromachines using 3D direct laser writing and selective physical vapor deposition of magnetic materials. Microtransporters with a wirelessly controlled Archimedes screw pumping mechanism are engineered. Spatiotemporally controlled collection, transport, and delivery of microparticles as well as magnetic nanohelices inside microfluidic channels are demonstrated.
