在单壁碳纳米管（SWNTs）的毛细管中制备了直径为1.0-1.4nm的Au、Ag、Pt和Pa纳米线。纳米线是单线；在某些情况下是结晶的。纳米线在酒精中的分散表现出不同波长的纵向等离子体吸收带，表明存在宽高比分布。在SWNT束的管间空间中观察到一种涉及金属层（类似于0.5 nm厚）的新现象。在一些制备中形成了由金属纳米粒子修饰的单壁碳纳米管。
Nanowires of Au, Ag, Pt, and Pa (1.0-1.4nm diam) have been produced in the capillaries of single-walled carbon nanotubes (SWNTs). The nanowire is single;crystalline in some cases. Dispersions of the nanowires in alcohol show longitudinal plasmon absorption bands at different wavelengths, suggesting the presence of a distribution of aspect ratios. A novel phenomenon involving the intercalation of metal layers (similar to 0.5 nm thick) in the intertubular space of SWNT bundles has been observed. SWNTs decorated by metal nanoparticles are formed in some of the preparations.
