Figure 3. Propulsion via Magnetic Fields Achieved Using Various Geometries.

Figure 3.

(A) Micro-/nanorobotics can mimic flagellar movements of prokaryotes via use of a helical structure. Application of external magnetic fields help to create corkscrew-like motion (reprinted from ref. 30 with permission, copyright 2021, The American Association for the Advancement of Science). (B) Three-link polypyrrole nanoswimmer comprising of magnetic nickel segments connected by flexible polymer heniges (reprinted from ref. 34 with permission, copyright 2015, American Chemical Society). (C) Janus microdimer moving via surface-assisted propulsion under a rotating magnetic field (reprinted from ref. 32 with permission, copyright 2021, Frontiers Media S.A.).
