Abstract

Design and fabrication of remote-controllable micromachines by femtosecond laser-induced two-photon polymerization (TPP) of novel ferrofluids resin composed of methacrylate groups modified Fe3O4 nanoparticles and photoresists is demonstrated. As two typical models, a micro-spring and a micro-turbine were successfully fabricated for precise motion control. The development of remotely controllable micro-nanomachines would shorten the distance between actionless micro-nanostructures and smart microrobots.
