A DNA nanodevice can be manipulated with an applied electric field Processes that occur at the nanometer scale have a tremendous impact on our daily lives. Sophisticated evolved nanomachines operate in each of our cells; we also, as a society, increasingly rely on synthetic nanodevices for communication and computation. Scientists are still only beginning to master this scale, but, recently, DNA nanotechnology (1)—in particular, DNA origami (2)—has emerged as a powerful tool to build structures precise enough to help us do so. On page 296 of this issue, Kopperger et al. (3) show that they are now also able to control the motion of a DNA origami device from the outside by applying electric fields.

纳米级设备的远程控制

DNA 纳米装置可以通过外加电场进行操作 发生在纳米尺度上的过程对我们的日常生活产生了巨大的影响。复杂的进化纳米机器在我们的每个细胞中运行；作为一个社会，我们也越来越依赖合成纳米设备进行通信和计算。科学家们才刚刚开始掌握这种规模，但最近，DNA 纳米技术 (1)——特别是 DNA 折纸 (2)——已经成为构建足够精确的结构以帮助我们做到这一点的强大工具。在本期第 296 页上，Kopperger 等人。(3) 表明他们现在也能够通过施加电场从外部控制 DNA 折纸装置的运动。
