我们演示了一个光学捕获物体--光桨轮的控制和旋转，其旋转方向垂直于光束轴。这与通常情况下围绕光束轴旋转的情况形成了对比。桨轮可以被光学驱动并移动到显微镜视野中的任何位置，这对于需要在特定位置和特定方向上控制流体流动的各种生物应用是有意义的。这在细胞内的信号转导研究中特别有意义，特别是当细胞是扁平的并展开在表面上时。
We demonstrate the control and rotation of an optically trapped object, an optical paddle-wheel, with the rotation direction normal to the beam axis. This is in contrast to the usual situation where the rotation is about the beam axis. The paddle-wheel can be optically driven and moved to any position in the field of view of the microscope, which can be of interest for various biological applications where controlled application of a fluid flow is needed in a particular location and in a specific direction. This is of particular interest in signal transduction studies in cells, especially when a cell is flat and spread out on a surface.
