Cancer poses a substantial threat and serious challenge to public human health, driving the promotion of sophisticated technologies for cancer therapy. While conventional chemotherapy has bottlenecks such as low delivery efficiency, strong toxic side effects, tumor enrichment barriers, magnetic micro/nanorobots (MNRs) emerge promising therapeutic candidates that provide alternative strategies MNR is kind human-made machine micro- or nanosized, reasonably designed, performs command tasks through self-actuated externally controlled propulsion mechanisms, which can be potentially applied in theranostics. Here, this review first introduces components constitute typical MNR, including body part, control function sensing part. Subsequently, elucidates representative fabrication methods construct MNRs from top-down approaches bottom-up approaches, covering injection molding, self-rolling, melt electrospinning writing, deposition, biotemplate method, lithography, assembling, 3D printing, chemical synthesis. Furthermore, focuses on multiple applications facing diagnosis treatment, encompassing imaging, quantification, drug release, synergy with therapies, cell manipulation, surgical assistance. Then, systematically elaborates biocompatibility biosafety MNRs. Finally, challenges faced by are discussed alongside future research directions.

Small-scale soft robots, capable of undulatory swimming propelled by distributed magnetic body torques, are numerically investigated under underwater conditions. These robots composed a stiff frame and sheet. The secures the ends sheet, preventing curling or rolling during swimming. To evaluate impact on dynamics, we systematically modulate frequency driving field, magnetization profiles robot, material mechanical properties fluid environment properties, wall proximity. Results indicate that all these factors significantly affect robot's velocity directional stability. Higher frequencies reduce velocity, while decreasing Regarding profiles, increasing number periods reduces segmented stability maintaining high velocity. Robots designed with stiffer materials concentrated near two exhibit faster robot maintains relatively stable motion achieves in very close proximity to wall, but it struggles maintain at even slightly greater distances. In shear-thinning fluids, higher due low-viscosity corridors surrounding its experiences reduced findings provide significant insights for design optimization small-scale controlled swimming, potential applications fields such as targeted drug delivery minimally invasive surgery.

Abstract Aquatic insects have developed versatile locomotion mechanisms that served as a source of inspiration for decades in the development small‐scale swimming robots. However, despite recent advances field, efficient, untethered, and integrated powering, actuation, control robots remains challenge due to out‐of‐equilibrium dissipative nature driving physical chemical phenomena. Here, we designed small‐scale, bioinspired aquatic locomotors with programmable deterministic trajectories integrate self‐propelled motors photoresponsive shape‐morphing structures. A Marangoni motor system is integrating structural protein networks self‐regulate release fuel photochemical liquid crystal network (LCN) actuators change their shape deform out surface water. While diffusion from regulates propulsion, deformation LCNs provides over directionality motion at air‐water interface. This approach gives access five different but interchangeable modes within single robot via morphing soft structure. The proposed design, which mimics gliding posture semiaquatic such water treaders, offers solutions autonomous untethered orthogonal power control.
