Remotely controlling the movement of small objects is desirable, especially for the transportation and selection of materials. Transfer of objects between liquid and solid surfaces and triggering their release would allow for development of novel material transportation technology. Here, we describe the remote transport of a material from a water film surface to a solid surface using quasispherical liquid marbles (LMs). A light-induced Marangoni flow or an air stream is used to propel the LMs on water. As the LMs approach the rim of the water film, gravity forces them to slide down the water rim and roll onto the solid surface. Through this method, LMs can be efficiently moved on water and placed on a solid surface. The materials encapsulated within LMs can be released at a specific time by an external stimulus. We analyzed the velocity, acceleration, and force of the LMs on the liquid and solid surfaces. On water, the sliding friction due to the drag force resists the movement of the LMs. On a solid surface, the rolling distance is affected by the surface roughness of the LMs.

使用液体大理石将材料从水转移到固体表面

期望远程控制小物体的运动，特别是对于材料的运输和选择。物体在液体和固体表面之间的转移并触发其释放将允许开发新颖的材料运输技术。在这里，我们描述了使用准球形液体大理石（LMs）将材料从水膜表面到固体表面的远程运输。光诱导的马兰戈尼流或空气流用于将LM推进水面上。当LM接近水膜边缘时，重力迫使它们滑下水边缘并滚动到固体表面上。通过这种方法，LM可以有效地在水上移动并放置在固体表面上。封装在LM中的材料可以在特定时间通过外部刺激释放。我们分析了速度，LM在液体和固体表面上的加速度和作用力。在水上，由于阻力产生的滑动摩擦会阻止LM的运动。在固体表面上，滚动距离受LM表面粗糙度的影响。
