胶体微电机：受控定向运动
Colloidal Micromotors: Controlled Directed Motion
摘要：
在这里，我们展示了一个合成的微型发动机，基于远程控制运动的胶体颗粒，这是由本地催化反应引起的。在长时间尺度的定向运动是通过将特殊设计的磁性包覆胶体置于弱磁场下的过氧化氢溶液中来实现的。通过改变溶液的浓度和改变施加的磁场的强度来控制颗粒的运动。这样的合成物体不仅可以用来理解基本的驱动过程，还可以用作生物环境中的小型发动机，例如，以可控的方式运输分子。
英文摘要：
Here we demonstrate a synthetic micro-engine, based on long-range controlled movement of colloidal particles, which is induced by a local catalytic reaction. The directed motion at long timescales was achieved by placing specially designed magnetic capped colloids in a hydrogen peroxide solution at weak magnetic fields. The control of the motion of the particles was provided by changes of the concentration of the solution and by varying the strength of the applied magnetic field. Such synthetic objects can then be used not only to understand the fundamental driving processes but also be employed as small motors in biological environments, for example, for the transportation of molecules in a controllable way.
