In the present study, we propose a magnetically controlled and electrically controlled magnetic liquid metal (MLM) method to achieve high-performance multiple manipulation of droplets. The prepared MLM has good active and passive deformability. Under the action of the magnetic field, controllable transport, splitting, merging, and rotation are realized. In addition, controllable electric field manipulation in alkaline and acidic electrolytes is realized. This simple preparation method can be applied to the precise and rapid control of the magnetic field and electric field at the same time. Compared with other droplet manipulation methods, we realized droplet manipulation independent of special surfaces. It has the advantages of easy implementation, low cost, and high controllability. It shows great application potential in the fields of biochemical analysis, microfluidics, drug transportation in complex limited space, and intelligent soft robots.
在本研究中，我们提出了一种磁控和电控磁流变液（MLM）方法，以实现高性能的液滴多相操控。所制备的 MLM 具有良好的主动和被动变形能力。在磁场作用下，实现了可控输运、分裂、合并和旋转。此外，还实现了在碱性和酸性电解液中可控的电场操控。这种简单的制备方法可应用于磁场和电场的精确和快速控制。与其他液滴操控方法相比，我们实现了独立于特殊表面的液滴操控。它具有易于实现、成本低和高可控性的优点。在生化分析、微流控、复杂受限空间内药物输送和智能软体机器人等领域具有巨大的应用潜力。
