Ferrybots are programmable PEGDA hydrogel microrobots that separate magnetic cores from cargo, achieving magnetic navigation with speeds up to 9000 mm/min and modular fusion.
- Why it matters: Untethered magnetic microrobots are hard to manufacture and functionalize because high magnetic loading can disrupt polymerization, and payload integration often forces full material redesign.
- What they did: The team used automated droplet-on-demand microfluidic flow-lithography to confine high-concentration ferrofluid cores, programming magnetic dose via core number and spacing, then fused independently formulated PEGDA 575 cargo modules.
- The result: Ferrybots showed magnetic-dose-dependent translation/rotation, branched-channel steering, and obstacle traversal, with sequential selective navigation of distinct populations and cargo modules enabling composition-dependent release and oxygen-responsive sensing in 1-mm-thick optical phantoms.
