For the latter, in our experience, manual control of the lead can be challenging, especially in presence of scar tissue, and may be associated with prolonged operating room (OR) time, patient discomfort, increased cost, and potential complications. By modulation of the external magnetic field input, the electrical field amplitude and shape could be adjusted as desired (Nan et al., 2008; Armin et al., 2012). This innovation offers several benefits for SCS electrode placement, including enhanced navigation control during tip placement, and the ability to position and reposition the lead in an outpatient setting. . Additionally, remote and contactless surgery reduces the risk of pathogen spread among healthcare workers and patients by decreasing direct contact, which is a desired effect in the light of the current Covid-19 pandemic (Zemmar et al., 2020).

Because of the small sizes of swarm agents, integrating actuators, Creating reconfigurable and recyclable soft microrobots that can execute multimodal locomotion has been a challenge due to the difficulties in material processing and structure engineering at a small. Micro- or nanorobots are small-scale devices designed to perform minimally-invasive interventions and are powered by external power sources (Colberg et al., 2014; Zeeshan et al., 2014; Rao et al., 2015; Chen et al., 2017a; Soto et al., 2021).

Copyright This short review intends to address recent progress on magnetically driven micro- and nanorobots developed in our laboratory and by other research groups. Magnetically actuated micro/nanorobots have attracted considerable research interests and have been developed rapidly in recent years because of their advantages, such as untouched control, insensitivity to biological substances, and precise positioning [23-26].Under the dominance of the magnetic fields, many investigators employed the micro/nanomachines assembled by DNA origami frameworks .

Copyright To be considered for neurostimulation, micro- and nanorobots must be able to generate an electrical field.

Candidates who have satisfactory results during the trial stage undergo permanent implantation of an implantable pulse generator (IPG), which is placed subcutaneously or subfascial in the gluteal or abdominal region (Rock et al., 2019). Electrode migration occurs in 1322% of SCS patients (Taccola et al., 2020), is more common with the less invasive percutaneous technique, and has been reported as the most frequent reason for repeat surgery (Turner et al., 2004), resulting in increased risk for the patient and additional operative time and cost. Copyright Applied Materials Today. 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). The use of MNS offers several potential benefits for SCS lead implantation, including precise navigation control during SCS lead placement, the ability for non-invasive post-operative re-adjustment of the SCS lead(s), decreased OR time and cost, reduced radiation exposure to the surgeon and patient and, in the light of the current Covid-19 pandemic, reduced direct contact with the patient and therefore a decreased risk for pathogen mitigation (Figure 2A) (Zemmar et al., 2020). These concepts are discussed to describe the interactions between micro/nanorobots and magnetic fields.

Spinal cord stimulation improves gait in patients with Parkinson's disease previously treated with deep brain stimulation. However, SCS implantation can be associated with a relatively high injury rate, ranking spinal cord stimulator placement as the third-highest leading cause of injury among all medical devices after metal hip prostheses and insulin pumps (Taccola et al., 2020). For magnetically driven micro/nanorobots, whether in vitro or in vivo, MRI is an effective tool for tracking the robot's position. Finally, infection related to SCS occurs in ~5% of the cases (Bendersky and Yampolsky, 2014). For magnetically driven micro/nanorobots, MRI is an efficient tool to track the position of MagRobots both in vitro and in vivo. Lead manipulation is optimized when MNS are combined with variable stiffness catheters that consist of multiple segments with independent stiffness control (Figure 2B) (Chautems et al., 2017). Micro- and nanorobots have the advantages of small size, low weight, large thrust-to-weight ratio, high flexibility, and high sensitivity. some rights reserved; exclusive licensee American Association for Affiliations.
