A critical factor that requires further investigation lies in the permanent attachment of the micro- and nanorobots on the dura mater through chemical modification with targeting ligands (Figure 2F), peptides or antibodies to avoid migration from stimulation site (Cheng et al., 2015; Tietjen et al., 2018; Scheepers et al., 2020) and offer regular neurostimulation for the patient. In the epidural space with minute amounts of biological fluids, micro- and nanorobot delivery will be complicated by surface friction and adhesion forces. These concepts are discussed to describe the interactions between micro/nanorobots and magnetic fields. (A) Overview of a spinal cord stimulation system.

While 30 mm radii have been precisely followed in the brain (Petruska et al., 2016), the steering radius of the tip in SCS is closer to 15 mm, which has to be tested in in vivo environments. 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).

Publisher Copyright: B., Le Goff-Mignardot C. G., Demesmaeker R., Komi S., Capogrosso M., et al.. (2018). In case of electrode migration, magnetic forces created by magnetic gradients perpendicular or parallel to the aligned field could be used to non-invasively and precisely move the electrode to the desired stimulation site. The magnetic field-induced actuation of colloidal nanoparticles has enabled tremendous recent progress towards microrobots, suitable for a variety of applications including targeted drug delivery. 10.1021/acs.nanolett.7b02383.

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. Additionally, optic fibers with fiber-Bragg-gratings sensors (FBGs) that reflect light at a wavelength that is proportional to mechanical (and thermal) strain on the fiber can be incorporated into the magnetic tip for contact-force measurements (Di Natali et al., 2016; Khan et al., 2019). Even with the lowest reported incidence of 2% (Gazelka et al., 2015), when considering the high volume of SCS procedures worldwide, this percentage still corresponds to a considerably high number of patients.
