“…[47]. Copyright 2015 John Wiley and Sons 同时, 对导电性碳管有选择性的还有 DNA [50] 、 RNA [51] 和卟啉 [52] 等几种常见的结构, 都是含有五元杂 环结构. 2003 年, Zheng 等 [50] 报道了 ssDNA 可以通过 π-π 相互作用缠绕在碳管表面, 实现对碳管的增溶.…”

“…随后, 他们还报道了 ssDNA 能选择性分离金属型和半导体型 碳管, 认为选择机理源自金属型和半导体型碳管的不同 极化率 [9] . Zaremba 等 [51] 报道了 tRNA 对直径较小的 CoMoCAT 碳管和 HiPCO 都有较好的增溶能力. Yan 等 [53] 报道了肝素钠对直径较大的碳管有较好的选择性 (图 17), 并且与碳管(8, 4)结合能最高.…”

Single-step extraction of small-diameter single-walled carbon nanotubes in the presence of riboflavin

“…Biopolymers such as DNA and RNA have been widely proven to disperse SWCNTs. Nucleic acids even exhibit sequence-dependent wrapping around nanotubes with different chiralities [12][13][14][15]. The remarkable biocompatibility of nucleic acids can support biomedical applications of such dispersions.…”

Structure-dependent performance of single-walled carbon nanotube films in transparent and conductive applications

“…Single-walled carbon nanotubes (SWCNTs) combine high conductivity with excellent optical and mechanical characteristics that make them a prospective component for novel electronic devices, e.g., transparent conductive films [1,2] and field effect transistors [3]. Significant effort has been devoted to advance the field: active development of methods for SWCNT dispersion [4,5], separation [6], and purification [7]; utilization of post-treatment [8] and doping procedures [9], and even patterning [10] were shown to enhance the nanotube performance. Nevertheless, aerosol (floatingcatalyst) chemical vapor deposition (CVD) method, which allows film fabrication by a dry transfer technique [11] avoiding laborious and expensive wet procedures, is within the spotlight.…”
