纳米技术的首要目标之一是分子级的功能设计，包括将分子随意排列成复杂的结构。实现这一目标的第一步是通过扫描探针显微镜（SPM）的发明，它首次将单原子和单分子操作付诸实践。将可控操作扩展到更大的分子有望成倍增加工程纳米结构的潜力。在这里，我们报告的SPM技术，使大分子吸附物的操作更加有效的增强。通过使用商业运动跟踪系统，我们耦合到亚埃的SPM尖端的精确定位的操作员的手的运动。从字面上移动的尖端，我们写在一个单层的大分子的纳米级结构，从而表明，我们的方法允许成功执行复杂的操作协议，即使当管理的相互作用行为的势能表面的操纵纳米级对象（S）在很大程度上是未知的。
One of the paramount goals in nanotechnology is molecular-scale functional design, which includes arranging molecules into complex structures at will. The first steps towards this goal were made through the invention of the scanning probe microscope (SPM), which put single-atom and single-molecule manipulation into practice for the first time. Extending the controlled manipulation to larger molecules is expected to multiply the potential of engineered nanostructures. Here we report an enhancement of the SPM technique that makes the manipulation of large molecular adsorbates much more effective. By using a commercial motion tracking system, we couple the movements of an operator's hand to the sub-angstrom precise positioning of an SPM tip. Literally moving the tip by hand we write a nanoscale structure in a monolayer of large molecules, thereby showing that our method allows for the successful execution of complex manipulation protocols even when the potential energy surface that governs the interaction behaviour of the manipulated nanoscale object(s) is largely unknown.
