We describe the use of seawater as fuel to propel Janus micromotors. The new micromotors consist of biodegradable and environmentally friendly magnesium microparticles and a nickel-gold bilayer patch for magnetic guidance and surface modification. Such seawater-driven micromotors, which utilize macrogalvanic corrosion and chloride pitting corrosion processes, eliminate the need for external fuels to offer efficient and prolonged propulsion towards diverse applications in aquatic environments.
我们描述了使用海水作为燃料来推动 Janus 微马达。这些新型微马达由可生物降解和环保的镁微颗粒以及用于磁性导向和表面改性的镍金双层贴片组成。这种海水驱动的微马达利用宏观电偶腐蚀和氯化物点蚀腐蚀过程，无需外部燃料即可提供高效且持久的推进力，适用于水生环境中的各种应用。
