由DNA稳定的碳纳米管制造的各向异性微布：用电极针一站式制造
Anisotropic micro-cloths fabricated from DNA-stabilized carbon nanotubes: one-stop manufacturing with electrode needles
摘要：
在各种解决方案为基础的方法来制造各向异性膜的定向碳纳米管（CNT），我们专注于介电泳组装方法使用AC电场在DNA稳定的CNT悬浮液。我们证明了使用电极针的一站式制造系统可以绘制尺寸为10-100 $μ$ m的各向异性DNA-CNT杂化膜（即，独立的DNA-CNT微布）从剩余的悬浮液中释放到大气中，同时保持结构有序。已经发现，最大偏振度（ca. 40 \%）可以实现从各种DNA-CNT混合物制造的微布。我们的研究结果表明，一站式的方法可以赋予生物相容性的缩小尺寸的碳纳米管薄膜和DNA稳定的碳纳米管微布直接连接到电极可以用于生物燃料电池的电子转移和/或酶活性。
英文摘要：
Among a variety of solution-based approaches to fabricate anisotropic films of aligned carbon nanotubes (CNTs), we focus on the dielectrophoretic assembly method using AC electric fields in DNA-stabilized CNT suspensions. We demonstrate that a one-stop manufacturing system using electrode needles can draw anisotropic DNA-CNT hybrid films of 10-100 $μ$m in size (i.e., free-standing DNA-CNT micro-cloths) from the remaining suspension into the atmosphere while maintaining structural order. It has been found that a maximal degree of polarization (ca. 40 \%) can be achieved by micro-cloths fabricated from a variety of DNA-CNT mixtures. Our results suggest that the one-stop method can impart biocompatibility to the downsized CNT films and that the DNA-stabilized CNT micro-cloths directly connected to an electrode could be useful for biofuel cells in terms of electron transfer and/or enzymatic activity.
