远程控制小物体的运动本身就是一个挑战，也可能允许整个系统的刺激控制。在这里，它描述了如何封装液体，称为液体弹珠，可以用简单的近红外激光或阳光在水面上移动。使用光而不是pH值或温度作为外部刺激，可以控制输送的位置、面积、时间、方向和速度。这种方法不仅可以运输包裹在液体大理石中的材料，还可以在外部刺激控制的特定地点和时间释放它们。此外，还表明液体弹珠可以作为光驱动的牵引引擎来推动或拉动物体。能够通过光远程运输和推/拉小物体，并根据需要控制活性物质的释放，应该开辟一个广阔的应用领域。
Remote control of the locomotion of small objects is a challenge in itself and may also allow for the stimuli control of entire systems. Here, it is described how encapsulated liquids, referred to as liquid marbles, can be moved on a water surface with a simple near-infrared laser or sunlight. Using light rather than pH or temperature as an external stimulus allows for the control of the position, area, timing, direction, and velocity of delivery. This approach makes it possible to not only transport the materials encapsulated within the liquid marble but also to release them at a specific place and time, as controlled by external stimuli. Furthermore, it is shown that liquid marbles can work as light-driven towing engines to push or pull objects. Being able to remotely transport and push/pull the small objects by light and control the release of active substances on demand should open up a wide field of conceivable applications.
