In general, when designing a magnetic catheter, one is faced with the challenge of catheter flexibility and the necessary amount of a magnetic volume to bend the tip and catheter rigidity for prevention of buckling during catheter advancement (Carey et al., 2006; Chautems et al., 2020). Rohani M., Kalsi-Ryan S., Lozano A. M., Fasano A. Actuation mechanisms of flagella-inspired MagRobots (i.e., corkscrew-like motion and traveling-wave locomotion/ciliary stroke motion) and surface walkers (i.e., surface-assisted motion), applications of magnetic fields in other propulsion approaches, and magnetic stimulation of micro/nanorobots beyond motion are provided followed by fabrication techniques for (quasi-)spherical, helical, flexible, wire-like, and biohybrid MagRobots. 2019 American Chemical Society.
