悬浮的单壁碳纳米管被用作通过蒸发沉积各种金属的基底。由于金属和纳米管之间的弱相互作用，许多类型的金属的沉积通常在纳米管上形成离散颗粒。然而，几乎任何金属的连续纳米线都是通过使用钛（一种与碳具有强相互作用的金属）作为纳米管上的缓冲层来获得的。金属纳米线可以是10 nm宽，连续长度高达几十微米。
Suspended single-wall carbon nanotubes are used as substrates for deposition of various metals by evaporation. Deposition of many types of metals normally forms discrete particles on nanotubes due to a weak interaction between the metals and nanotubes. However, continuous nanowires of virtually any metal are obtained by using titanium, a metal with strong interaction with carbon, as a buffer layer on nanotubes. The metal nanowires can be ⩽10 nm wide with continuous length up to tens of microns.
