Carbon can bond in different ways to construct structures with completely different properties. The sp 2 hybridization of carbon builds a layered construction with weak out-of-plane bonding of the van der Waals form and strong in-plane bounds. Video from Nova s38e09 showing impressive production of long carbon nanotube strands. Abstract: The unique properties of carbon nanotubes (CNTs) (such as their high surface to volume ratios, enhanced conductivity and strength, biocompatibility, ease of functionalization, optical properties, etc.) have led to their consideration to serve as novel drug and gene delivery carriers. Carbon nanotubes (CNTs) are usually delivered into the lungs of laboratory animals by inhalation, instillation or aspiration.No systemic toxicity of multi-walled carbon nanotubes (MWCNTs) could be observed in an inhalation study of several weeks with rats [2].

11 Jan 2018 The carbon nanotube, discovered by Sumio Iijima in 1991, is one of the allotropes of carbon, apart from diamond, graphite, and fullerenes.((“

Some nanotubes have a property called chirality, an expression of longitudinal twisting. Carbon nanotubes are large molecules, made from a repeating pattern of sp2 hybridized carbon atoms in a hexagonal arrangement, wrapped into a cylinder of approximately 2.5–100 nm in diameter. Carbon nanotubes are single or multi-walled depending on the number of carbon sheets rolled together, while the ends are capped by a hemispherical carbon arrangement as seen in fullerenes. Carbon nanotubes are a tube like material mainly made up of carbon. Only carbon nanotubes are the macromolecules of graphite consisting of sheets of carbon, which is weaved into the cylinder. Graphite sheets look like a hexagonal in shape Nano carbon tubes are about 2 millimetres long and these are one hundred times as stiff as steel. There is increasing interest in the unique biological and medical properties of carbon nanotubes (CNTs), and it is expected that biomaterials incorporating CNTs will be developed for clinical use.
