Design and Modeling of a Versatile Micro/Nanomotor Propulsion System by Light-Guided Dielectrophoresis
摘要：
开发能够以设计的机械运动有效地响应外部刺激的活性材料是阻碍纳米机器人和纳米机器人实现的主要障碍之一。在这里，我们提出了一种创新的工作机制，允许通过简单的可见光刺激的AC介电泳的半导体微/纳米电机的多折叠平移运动控制。通过考虑Maxwell-Wagner弛豫和双电层荷电效应的模型化方法，研究了不同几何形状的半导体颗粒在水悬浮液中的介电泳力.在此基础上，我们设计了一个操作系统，通过调节电场中的光强，可以同时实现半导体微/纳米电机的自动传输和定向。该研究为开发具有高通用性和可控性的新型微/纳米机器平台提供了指导。它与纳米机器人和纳米器件组装有关。
英文摘要：
To develop active materials that can efficiently respond to external stimuli with designed mechanical motions is one of the major obstacles that have hindered the realization of nanomachines and nanorobots. Here, we propose an innovative working mechanism that allows multifold-translational-motion control of semiconductor micro/nanomotors by AC dielectrophoresis with simple visible-light stimulation. We study the dielectrophoresis forces on semiconducting particles of various geometries in aqueous suspension by modeling with the consideration of both the Maxwell-Wagner relaxation and electrical-double-layer-charging effect. With the obtained understanding, we rationally design a manipulation system that can versatilely transport semiconductor micro/nanomotors and orient them towards desired directions at the same time by tuning the light intensity in an electric field. This research may guide the development of a new type of micro/nanomachine platform with high versatility and control. It is relevant to nanorobotics and nanodevice assembly.
