Ultrapure SWCNT for biomedical and biotechnological applications especially for their interesting use in the delivery of therapeutically active molecules to targeted cells. The interaction between cells and this nanomaterial is a critical feature that is responsible for the pharmacological effect as well as for any eventual toxicity. The latter aspect, in this manuscript evaluated a few parameters that seem to be involved in the cytotoxic profile of Ultrapure SWCNT and Multi-walled (MWCNTs) nanotubes), such as their sidewall functionalization, tubes’ length, solubility, concentration and purity. Ultrapure SWCNT totally dispersible, carbon nanotubes not only display lack of toxicity in the range of concentrations normally used (10-150 μg/ml), but they also pave the way for an extensive use of this material for several biomedical purposes.

Semiconducting Ultrapure SWCNT are promising materials for charge transport in field-effect transistor (FET) devices. In order to develop short channel s-SWCNT FETs with high on/off ratios relevant for logic applications, ultra-pure s-SWCNTs of 99.99999% semiconducting purity and higher are needed. The sorting of Ultrapure SWCNT, but most reports have only reached semiconducting purity levels near 99%. In addition, aligned arrays of Ultrapure SWCNT have the potential to improve the mobility and current output of FET. The purity and electronic transport properties of aligned arrays of polyfluorene-sorted s-SWCNTs in FET devices.

Ultrapure SWCNT are a natural choice as gas sensor components given their high surface to volume ratio, electronic properties and capability to mediate chemical reactions. However, a realistic assessment of the interaction of the tube wall and the adsorption processes during gas phase reactions has always been elusive. Making use of ultra-clean single-walled carbon nanotubes, we have followed the adsorption kinetics of NO$_2$ and found a physisorption mechanism.

Ultrapure SWCNT is reflected in a production capacity that presently exceeds several thousand tons per year. Currently, bulk Ultrapure SWCNT powders are incorporated in diverse commercial products ranging from rechargeable batteries, automotive parts, and sporting goods to boat hulls and water filters. Advances in CNT synthesis, purification, and chemical modification are enabling integration of CNTs in thin-film electronics and large-area coatings. Although not yet providing compelling mechanical strength or electrical or thermal conductivities for many applications, CNT yarns and sheets already have promising performance for applications including supercapacitors, actuators, and lightweight electromagnetic shields.

Ultrapure SWCNT unique combination of optical, thermal, mechanical, and electrical properties has led to substantial development activities in numerous applications such as composites, nanoelectronics, chemical and biosensors, and platforms for drug delivery. The performance of Ultrapure SWCNT in each of these applications depends on the properties and purity of the SWCNT material. Variability in these materials can occur, depending on the manufacturing process used (e.g., chemical vapor deposition, laser ablation) and the conditions within a manufacturing run (e.g., temperature, catalyst concentration).
