“…In our recent report on the production of SWNTs with improved oxidation resistance, we suggest that the bowl-like cathode possesses a defect-healing effect which can be induced by in-situ annealing. 17 The very high oxidation resistance of DWNTs in this work may be partially due to the same factors.…”

High-quality double-walled carbon nanotube (DWNT) super bundles were selectively grown above a bowllike cathode by arc discharge in a hydrogen-free atmosphere. These DWNTs can resist high-temperature (up to 720°C) oxidation in air without additional annealing even after acid treatment, which is due to an in-situ defect-healing effect of the bowl-like cathode and the absence of reactive gases during arc discharge. Selective formation of DWNTs is ascribed to the increased presence of carbon clusters in the enlarged hot plasma region inside the cathode and optimized composition of the catalysts.

Although many methods have been documented for carbon nanotube (CNT) synthesis, still, we notice many arguments, criticisms, and appeals for its optimization and process control. Industrial grade CNT production is urgent such that invention of novel methods and engineering principles for large-scale synthesis are needed. Here, we comprehensively review arc discharge (AD) and laser ablation (LA) methods with highlighted features for CNT production. We also display the growth mechanisms of CNT with reasonable grassroots knowledge to make the synthesis more efficient. We postulate the latest developments in engineering carbon feedstock, catalysts, and temperature cum other minor reaction parameters to optimize the CNT yield with desired diameter and chirality. The rate limiting steps of AD and LA are highlighted because of their direct role in tuning the growth process. Future roadmap towards the exploration of CNT synthesis methods is also outlined.Electronic supplementary materialThe online version of this article (doi:10.1186/s11671-016-1730-0) contains supplementary material, which is available to authorized users.

“…[74,75] Laser polarization angle-dependent Raman intensity profiling is particularly suited to determine CNT orientation with respect to underlying substrates or nanotube-containing matrices. [76][77][78] Sem-SWNTs, when dispersed individually with the help of surfactants or other biomolecules, show weak photoluminescence resonant with their electronic transitions.…”

The unique electronic and optical properties of carbon nanotubes, in conjunction with their size and mechanically robust nature, make these nanomaterials crucial to the development of next-generation biosensing platforms. In this Review, we present recent innovations in carbon nanotube-assisted biosensing technologies, such as DNA-hybridization, protein-binding, antibody-antigen and aptamers. Following a brief introduction on the diameter-and chirality-derived electronic characteristics of single-walled carbon nanotubes, the discussion is focused on the two major schemes for electronic biodetection, namely biotransistor-and electrochemistry-based sensors. Key fabrication methodologies are contrasted in light of device operation and performance, along with strategies for amplifying the signal while minimizing nonspecific binding. This Review is concluded with a perspective on future optimization based on array integration as well as exercising a better control in nanotube structure and biomolecular integration.
