Abstract

Droplet actuation simplifies the handling of various reagents or samples and can be applied to a wide range of fields, including chemistry, biology, biomedical, and others. This paper presents a programmable droplet control system based on a magnetoelastic membrane and electromagnetic pillar array. Different magnetic blocks with different magnetization directions were designed on the silicone rubber membrane, and the magnetoelastic membrane deformed under the magnetic field generated by the array of electromagnetic pillars. By combining the gravitational forces of the droplet and the deformation of the magnetic membranes, the motion of the droplet can be controlled. Furthermore, the surface of membranes was ablated with a laser machine to impart superhydrophobic properties. The simulation results show that with the different magnetic fields, the droplet can move lengthwise, widthwise, and diagonally in the horizontal plane, and multiple droplets can be merged and mixed. In contrast to the traditional droplet control method, the droplet programmable movement control system utilizing superhydrophobic magnetoelastic membranes and an electromagnetic pillar array has better stationarity, flexibility and does not affect the basic properties of the droplets.
基于磁控的可编程液滴操作平台设计
液滴驱动简化了各种试剂或样品的处理,可应用于广泛的领域,包括化学,生物学,生物医学等。提出了一种基于磁弹性膜和电磁柱阵列的可编程液滴控制系统。在硅橡胶膜上设计不同磁化方向的磁块,使磁弹性膜在电磁柱阵列产生的磁场下发生变形。通过结合液滴的重力和磁膜的变形,可以控制液滴的运动。此外,用激光机器烧蚀膜的表面以赋予其超疏水性。仿真结果表明,在不同的磁场作用下,液滴可以在水平面上进行纵向、横向和对角线运动,并且可以实现多个液滴的合并和混合。与传统的液滴控制方法相比,利用超疏水磁弹性膜和电磁柱阵列的液滴可编程运动控制系统具有更好的平稳性和灵活性,并且不影响液滴的基本性质。
