将单、双顺磁性胶体粒子放置在磁性正方形图案上方，并围绕图案的高对称性方向通过外加磁场处理来驱动。外部磁场和图案的磁场将胶体限制在平行于图案的晶格矢量的通道中。外场的进动导致磁势沿磁道方向的行进极小值。在足够高的调制频率下，只有两个胶体对外场做出响应并沿着沿车道的行进极小值的方向移动，而单个胶体不能跟随并保持静止。我们展示了双体如何诱导单个胶体的协调运动，形成由双体运输的几个单一胶体链组成的胶体列车。
Single and double paramagnetic colloidal particles are placed above a magnetic square pattern and are driven with an external magnetic field processing around a high symmetry direction of the pattern. The external magnetic field and that of the pattern confine the colloids into lanes parallel to a lattice vector of the pattern. The precession of the external field causes traveling minima of the magnetic potential along the direction of the lanes. At sufficiently high frequencies of modulation, only the doublets respond to the external field and move in direction of the traveling minima along the lanes, while the single colloids cannot follow and remain static. We show how the doublets can induce a coordinated motion of the single colloids building colloidal trains made of a chain of several single colloids transported by doublets.
