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
