Abstract

Single-wall fullerene nanotubes were converted from nearly endless, highly tangled ropes into short, open-ended pipes that behave as individual macromolecules. Raw nanotube material was purified in large batches, and the ropes were cut into 100- to 300-nanometer lengths. The resulting pieces formed a stable colloidal suspension in water with the help of surfactants. These suspensions permit a variety of manipulations, such as sorting by length, derivatization, and tethering to gold surfaces.

摘要

单壁富勒烯纳米管从几乎无限长、高度缠结的绳索状转变为短的、开口的管状物，其表现如同单个大分子。原始纳米管材料被大批量纯化，绳索状纳米管被切割成100至300纳米长的片段。借助表面活性剂，这些片段在水中形成了稳定的胶体悬浮液。这些悬浮液允许进行各种操作，例如按长度分类、衍生化以及连接到金表面。
