本文介绍了特斯拉电泳（Teslaphoresis），即物质通过特斯拉线圈的定向运动和自组装，并使用单壁碳纳米管（CNTs）研究了这种电动现象。传统的使用电场的物质定向自组装被限制在小尺度结构上，但是通过Teslaphoresis，我们通过使用特斯拉天线来创建一个投射到自由空间的梯度高压力场来超越这一限制。碳纳米管放置在Teslaphoretic（TEP）场致伸缩和自组装成线，从纳米尺度到宏观尺度的跨度，迄今为止最长的是15厘米。我们表明，TEP场不仅可以指导长纳米管线在远程（>30 cm）的自组装，而且还可以为基于纳米管的LED电路无线供电。此外，个体化的CNT自组织以形成与TEP场高保真对准的长平行阵列。因此，Teslaphoresis是有效的自下而上的宏观尺度的定向自组装。
This paper introduces Teslaphoresis, the directed motion and self-assembly of matter by a Tesla coil, and studies this electrokinetic phenomenon using single-walled carbon nanotubes (CNTs). Conventional directed self-assembly of matter using electric fields has been restricted to small scale structures, but with Teslaphoresis, we exceed this limitation by using the Tesla antenna to create a gradient high-voltage force field that projects into free space. CNTs placed within the Teslaphoretic (TEP) field polarize and self-assemble into wires that span from the nanoscale to the macroscale, the longest thus far being 15 cm. We show that the TEP field not only directs the self-assembly of long nanotube wires at remote distances (>30 cm) but can also wirelessly power nanotube-based LED circuits. Furthermore, individualized CNTs self-organize to form long parallel arrays with high fidelity alignment to the TEP field. Thus, Teslaphoresis is effective for directed self-assembly from the bottom-up to the macroscale.
