单束碳纳米管已经从悬浮液中选择性地沉积到亚微米电极上。我们表明，它是可能的，以控制一个单一的束通过使用银作为电极材料，不像Au，强烈相互作用的羧基官能化的碳纳米管的捕获。Au或Ag电极之间的束的良好对准出现在高于1 kHz的频率下，其中用Ag电极形成上级接触。
Single bundles of carbon nanotubes have been selectively deposited from suspensions onto sub-micron electrodes with alternating electric fields. We show that it is possible to control the trapping of a single bundle by the use of Ag as electrode material which, unlike Au, strongly interacts with the carboxyl functionalized carbon nanotubes. Excellent alignment of the bundles between Au or Ag electrodes occurs at frequencies above 1 kHz, with superior contacts being formed with Ag electrodes.
