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...
Hongbo Sun and co‐workers report on p. 3204 on the synthesis of ferrofluids, stable colloidal mixtures composed of magnetic nanoparticles suspended in a photopolymerizable resins as carriers, which were then utilized as precursor materials for femtosecond laser direct writing of remotely controllable micro‐/nanomachines. Such photopolymerizable ferrofluid‐enabled machines can be envisioned performing...
