磁性液态金属（MLM）是一种磁性颗粒与镓基液态金属的混合物，它利用了流动性、高导热/导电性、生物相容性和磁性的非常规组合。近年来，从材料到应用，对传销的研究急剧增加。单个或多个传销可以精确定位，也可以作为搬运其他物体的载体。传销还用于生物医学应用，例如通过热疗和肿瘤上精确输送癌症药物的癌症治疗，或杀死细菌的抗菌涂层。在电子应用中，mlm用于磁场驱动的金属线图图化，可重构互连，电子纹身和可重构电磁波屏蔽。相变（固体/液体）的传销增加了另一个独特的能力，变形。微/纳米机器人和传直销的创新结合具有巨大的潜力，可以为各种各样的应用带来前所未有的颠覆性技术，包括自变形形状恢复机器人，高度局部化的癌症治疗，以及可重构的隐身/伪装等。本文从传销的材料、制备方法、传销的运动、传销的应用和未来展望等方面全面综述了传销的最新发展。
Magnetic liquid metal (MLM) is a mixture of magnetic particles with gallium‐based liquid metals which utilizes an unconventional combination of fluidity, high thermal/electrical conductivity, biocompatibility, and magnetism. Recently, from materials to applications, studies on MLMs have drastically increased. Single or multiple MLMs can be precisely positioned or can act as a carrier for handling other objects. MLMs are also used in biomedical applications such as cancer treatment by hyperthermia and precision delivery of cancer drugs on tumors, or antibacterial coating which kills bacteria. In electronics applications, MLMs are used for magnetic field‐driven patterning of metallic lines, reconfigurable interconnects, electronic tattoos, and reconfigurable electromagnetic wave shielding. Phase change (solid/liquid) of MLMs adds another unique capability, morphing. A combination of innovations in the micro/nano robots and MLMs has huge potential to bring an unprecedented disruptive technology for a wide variety of applications including self‐morphing shape‐recovery robots, highly localized cancer treatment, and reconfigurable stealth/camouflage, among others. This article comprehensively reviews recent developments in MLMs from the materials to methods of preparation, locomotion of MLMs, their applications, and future outlooks.
