Sequence plays an important role in self-assembly of 3D complex structures, particularly for those with overlap, intersection, and asymmetry. However, it remains challenging to program the sequence of self-assembly, resulting in geometric and topological constrains. In this work, a nanoscale, programmable, self-assembly technique is reported, which uses electron irradiation as “hands” to manipulate the motion of nanostructures with the desired order. By assigning each single assembly step in a particular order, localized motion can be selectively triggered with perfect timing, making a component accurately integrate into the complex 3D structure without disturbing other parts of the assembly process. The features of localized motion, real-time monitoring, and surface patterning open the possibility for the further innovation of nanomachines, nanoscale test platforms, and advanced optical devices

顺序折纸的电子辐照驱动纳米手。

序列在3D复杂结构的自组装中起着重要作用，尤其是对于那些具有重叠，交叉和不对称的结构。然而，对自组装序列进行编程仍然具有挑战性，从而导致几何和拓扑约束。在这项工作中，报道了一种纳米级，可编程的，自组装技术，该技术使用电子辐照作为“手”以所需顺序操纵纳米结构的运动。通过以特定顺序分配每个单独的组装步骤，可以以完美的时机选择性地触发局部运动，从而使组件准确地集成到复杂的3D结构中，而不会干扰组装过程的其他部分。局部运动，实时监控和表面图案化等功能为纳米机器的进一步创新打开了可能性，
