This review introduces fundamental concepts and advantages of magnetic micro/nanorobots (termed here as "MagRobots") as well as basic knowledge of magnetic fields and magnetic materials, setups for magnetic manipulation, magnetic field configurations, and symmetry-breaking strategies for effective movement. Maxwell coil, uniform saddle coil, and gradient saddle coil. Employed in two industrial projects of Dr.Habib Badri Ghavifekr, which are about . Magnetic navigation systems (MNS) are an emerging technology permitting precise and dynamic steering of surgical probes (Zemmar et al., 2020). 2018 WILEY-VCH Verlag GmbH and Co. KGaA, Weinheim. Sufficient flexibility of the catheter tip is necessary to provide steering freedom and after removal of the magnetic field, stress-relaxation (micro-shattering of the electrode tip) should be avoided (Jonathan and Groen, 2005; Petruska et al., 2016).

This work reports a new type of magnetic nanorobot, a symmetric multilinked two-arm nanoswimmer, capable of efficient "freestyle" swimming at low Reynolds numbers, and demonstrates for the first time that the nonplanar propulsion gait due to the cooperative "Freestyle" stroke of the two magnetic arms can be powered by a plane oscillatory magnetic field.

For semi-automated procedures, haptic feedback devices could be linked with FBGs signals to provide a sense of touch to the surgeons' hand (El Rassi and El Rassi, 2020). Applications of MagRobots in targeted drug/gene delivery, cell manipulation, minimally invasive surgery, biopsy, biofilm disruption/eradication, imaging-guided delivery/therapy/surgery, pollution removal for environmental remediation, and (bio)sensing are also reviewed. 2017, 17, 50925098. from ref (64). Smart dental materials for antimicrobial applications. Open questions include whether small-scale robots can generate an electrical field sufficient to activate neuronal tissue, as well as testing precise navigation, placement, anchoring, and biodegradation of micro- and nanorobots in the in vivo environment. The percutaneous lead placement technique necessitates fluoroscopic guidance during needle insertion and lead placement phases. An advantage of MNS would be that SCS leads could be placed outside an operating room (similar to a lumbar puncture, which can be done in a physician's office) through a Touhy needle into the epidural space.
