Gastric perforation refers to the complete rupture of gastric wall, leading extravasation contents into thoracic cavity or peritoneum. Without timely intervention, expulsion may culminate in profound discomfort, exacerbating inflammatory process and potentially triggering perilous sepsis. In clinical practice, surgical suturing endoscopic closure procedures are commonly employed. Magnetic-driven microswarms have also been employed for sealing gastrointestinal perforation. However, intervention entails significant risk bleeding, while poses risks inadequate need subsequent removal clips. Moreover, efficacy is limited as they merely adhere perforated area, their effect diminishes upon magnetic field. Herein, we present a Fe&Mg@Lard-Paraffin micromotor (LPM) constructed from mixture lard paraffin coated with magnesium (Mg) microspheres iron (Fe) nanospheres sutureless perforations. Under control rotating field, this demonstrates precise over its movement on mucosal folds accurately targets area. The phase transition induced by high-frequency magnetothermal causes composed mixed oil change solid liquid phase. Mg subsequently exposed acidic acid environment produce protonation reaction, which turn generates hydrogen (H2) bubble recoil. Through Mg-based micropower traction, part could be pushed perforation, it would then solidify seal Experimental results show that can achieve long-term (>2 h) sealing. This innovative approach holds potential improving outcomes management.

Microrobots with different structures can exhibit multiple propulsion mechanisms under external magnetic fields. Swarms dynamically assembled by microrobots inherit the advantages of single microrobots, such as degradability and small dimensions, while also offering benefits like scalability high flexibility. With control fields, these swarms demonstrate diverse perform precise actions in complex environments. Therefore, relationship between their is a significant area study. This paper reviews examining structural design, methods, mechanisms, practical applications. At first, we introduce design including materials manufacturing methods. Then, describe field generation systems, gradient, rotating, oscillating characteristics. Next, analyze individual way assemble into swarm an field, which illustrates swarms. Finally, discuss application water purification targeted delivery, summarize current challenges future work, explore directions.
