Remotely controlling the movement of small objects is a challenging research topic, which can realize the transportation of materials. In this study, remote locomotion control of particle-stabilized bubbles on a planar water surface by near-infrared laser or sunlight irradiation is demonstrated. A light-induced Marangoni flow was utilized to induce the locomotion of the bubbles on water surface, and the timing and direction of the locomotion can be controlled by irradiation timing and direction on demand. The velocity, acceleration, and force of the bubbles were analyzed. It was also confirmed that the bubbles can work as light-driven towing engines to pull other objects. Furthermore, it was demonstrated that the bubbles can work as an adhesive to bond two solid substrates by application of compressive stress under water. Such remote transport of the materials, pulling of the objects by light, and controlling the release of gas on demand should open up a wide field of conceivable applications.

气泡的光驱运动。
远程控制小物体的运动是一个具有挑战性的研究课题，可以实现物料的运输。在这项研究中，证明了通过近红外激光或日光照射对水平面上稳定的颗粒进行远程运动控制。利用光诱导的马兰戈尼流来引起气泡在水表面上的运动，并且该运动的时间和方向可以通过根据需要的照射时间和方向来控制。分析了气泡的速度，加速度和作用力。还证实了气泡可以作为光驱牵引引擎来拉动其他物体。此外，已经证明，通过在水下施加压缩应力，气泡可以充当粘合剂来粘合两个固体基材。
