Manipulation of swarm ferrofluid droplets on liquid surface
Source abstract
Abstract
Manipulation of small liquid droplets is critical for many types of research and applications in the field of chemistry, biology, etc. Many methods based on different working principles were proposed to manipulate liquid droplets. Among them, magnetic manipulation is widely used because of its safety and contactless feature. However, current control strategies mainly focus on hydrophobic or superhydrophobic solid surfaces requiring costly special treatments and being vulnerable to external pollution, which is an obstacle for surface reusing. Besides, the existing technologies are difficult to balance size and quantity of liquid droplets. Here, we propose high precision, resolution and the manipulation control methods for achieving manipulation of both single and swarm ferrofluid droplets. Utilizing the proposed methods, we can achieve the letter writing on the liquid surface. The proposed method offers an efficient strategy for manipulation of ferrofluid droplets.
