“…The further statistical analysis of the angular distribution between the two rows of SNAs demonstrated a s‐shaped distribution, indicating that our method enables the parallel alignment and angular control of the CNTs on the DNA‐origami substrate. Notably, compared with other experimental technologies including biological, chemical, and integrated method, our method showed a higher assembly efficiency, smaller assembly distance with high controllability (Figure f and Supporting Information, Table S1).…”

Aligning carbon nanotubes (CNTs) is a key challenge for fabricating CNT‐based electronic devices. Herein, we report a spherical nucleic acid (SNA) mediated approach for the highly precise alignment of CNTs at prescribed sites on DNA origami. We find that the cooperative DNA hybridization occurring at the interface of SNA and DNA‐coated CNTs leads to an approximately five‐fold improvement of the positioning efficiency. By combining this with the intrinsic positioning addressability of DNA origami, CNTs can be aligned in parallel with an extremely small angular variation of within 10°. Moreover, we demonstrate that the parallel alignment of CNTs prevents incorrect logic functionality originating from stray conducting paths formed by misaligned CNTs. This SNA‐mediated method thus holds great potential for fabricating scalable CNT arrays for nanoelectronics.

“…[27,28] Recent breakthroughs on nanofabrication and large-scale integration of CNT-based transistors also confirmed the material's compatibility with wafer-scale fabrication processes, and solved the bottleneck issues of CNT-based electronics moving towards practical uses. [29][30][31] For fluid and ion transport, the nanotubular structure of CNTs can also serve as high-performance artificial ionic nanochannels. [32,33] Previous studies have demonstrated that fluid and ion transport in CNT nanochannels is ultra-efficient, [32,34] which could potentially improve the performance of ionotronics.…”

Controlled ion transport through ion channels of cell membranes regulates signal transduction processes in biological systems and has also inspired the thriving development of ionic electronics (ionotronics or iontronics) and biocomputing. However, for constructing highly integrated ionic electronic circuits, the integration of natural membrane‐spanning ion channel proteins or artificial nanomembrane‐based ionic diodes into planar chips is still challenging due to the vertically arranged architecture of conventional nanomembrane‐based artificial ionic diodes. Here, a new design of ionic diode is reported, which allows chip‐scale integration of ionotronics, based on horizontally aligned nanochannels made from multiwalled carbon nanotubes (MWCNTs). The rectification of ion transport through the MWCNT nanochannels is enabled by decoration of oppositely charged polyelectrolytes on the channel entrances. Advanced ionic electronic circuits including ionic logic gates, ionic current rectifiers, and ionic bipolar junction transistors (IBJT) are demonstrated on planar nanofluidic chips by stacking a series of ionic diodes fabricated from the same bundles of MWCNTs. The horizontal arrangement and facile chip‐scale fabrication of the MWCNT ionic diodes may enable new designs of complex but monolithic ionotronic systems. The MWCNT ionic diode may also prove to be an excellent platform for investigation of electrokinetic ion transport in 1D carbon materials.

“…In particular, the unique electron‐regulating property of carbon nanotubes has revolutionize the way modern computation is carried out. Rather than silicon‐based computer processors, we have just become capable of running a 16‐bit computer processor solely based on carbon nanotubes . Although only simple computation is demonstrated currently, such carbon nanotubes (CNT)‐based processor holds an extremely promising future since it can theoretically run faster but cost lower energy than the commercialized silicon‐based technology.…”

Carbon is the central element driving the evolution of our human society towards prosperity over several historical stages. As for now, we are in a stage of blossoming sciences and technologies related to carbon materials, as a result of which our evergrowing energy demand has been largely satisfied. Yet, the expected rise of carbon energy consumption and the emerging environmental concerns have prevented us from being optimistic. To build a sufficiently powered future, we have been revolutionizing our ways of carbon energy utilization by discovering and designing new carbon structures, exploring and enhancing their unique physicochemical properties, and pursuing environmentally friendly strategies. Emerging structures such as graphene and sp-bonded C 18 have allowed us to discover carbon's promising properties such as energy storage and superconductivity, while green energy solutions such as fuel cells and CO 2 reduction are working synergistically to purify the ecospheric carbon cycle. Therefore, this essay timely discusses related carbon sciences and technologies that have been the milestones shaping our energy consumption, based on which our energy future can be envisioned to be green and prosperous.
