Description:

Liquids form the biggest portion of this world and our body. Life grows in liquids

in tiny scales and the microfluidics field tries to offer methods to study liquids

in a similar scale. We see water droplets on different surfaces everywhere,

thus one of the general questions we face: is it possible to move or manipulate

a water droplet on a surface in the direction we wish.

This work targets this question, and asks about how to move water droplets on

a surface with another liquid, a synthesized magnetic liquid, in a robust and

controllable way. This work shows how we can control the interaction between

two liquids in order to move water droplets in a programmable manner, on

a surface. Moreover, it presents a novel approach to use this magnetic liquid

for micro-structuring surfaces, will be used for passive manipulation of water

droplets by altering their interaction with the surface.
