A Laser Fabrication of Magnetic Micromachines by Using Optimized Photosensitive Ferrofluids

الملخص EN

We report here a laser fabrication of magnetic micromachines by using optimized photosensitive ferrofluids.

Fe3O4 nanoparticles were prepared by thermal decomposition and subsequent ligand exchange.

And then, they were dispersed into photoresist.

As a representative illustration, a magnetic microturbine with high surface flatness was fabricated, and its rotation speed could reach as high as 400 rpm under revolving magnetic field.
