Abstract

A single-walled carbon nanotube self-suspended network of exceptionally low density is formed by DNA-streptavidin-assisted assembly where the DNA complex serves as a cross-shaped point connector. The macroscopic nanotube aerogel is conductive and luminescent and presents an excellent scaffold for subsequent functionalization. For example, platinum and titanium dioxide coating of the nanotube network is demonstrated.

摘要

通过 DNA-链霉亲和素辅助组装形成了异常低密度的单壁碳纳米管自支撑网络，其中 DNA 复合物用作十字形点连接器。宏观碳纳米管气凝胶是导电和发光的，并为随后的功能化提供了极好的支架。例如，展示了对纳米管网的铂和二氧化钛涂层。
