我们已经开发了一种方法来沿结构将碳纳米管(CNT)定向或弯曲到所需的方向。新方法利用催化剂相对于结构的仔细定位，使从催化剂中生长的碳纳米管从结构中受到有效的范德华力。力使碳纳米管束沿所需的方向生长。例如，从洞中出来的碳纳米管束可以向右或向左弯曲，这取决于底部的催化剂图案。这种方法有望实现未来电子器件的三维碳纳米管布线。
We have developed a method of directing or bending carbon nanotubes (CNTs) in the desired direction along a structure. The new method utilizes careful positioning of a catalyst with respect to the structure, so that the CNTs growing from the catalyst experience an effective van der Waals force from the structure. The force causes a CNT-bundle to grow in the desired direction. For instance, a CNT-bundle coming out of a hole can be bent to the right or left depending on the catalyst patterning at the bottom. This approach is promising for achieving three-dimensional CNT wiring for future electronic devices.
