3D-printed machines that manipulate microscopic objects using capillary forces
传统的3D打印技术难以满足对微观和纳米级产品日益增长的需求,因为如此微小的事物非常难以操纵。本工作发明了一种利用水-空气界面抓取和操纵微观物体的3D打印微型机器,通过改变浮动对象周围的边界形状,通过控制其润湿性动态地调节毛细作用力,以可编程的二维模式移动物体。本文发表于Nature期刊。
“这篇文章的创意和优雅深深地吸引了我。利用毛细管力来“驱动”机器并不是一件显而易见的事情,但它工作得很好,可以从非常简单的前体产生令人惊讶的复杂运动和模式。”
