Nanotube
Encyclopedia
A nanotube is a nanometer-scale tube-like structure. It may refer to:
- Carbon nanotubeCarbon nanotubeCarbon nanotubes are allotropes of carbon with a cylindrical nanostructure. Nanotubes have been constructed with length-to-diameter ratio of up to 132,000,000:1, significantly larger than for any other material...
- Inorganic nanotubeInorganic nanotubeAn inorganic nanotube is a cylindrical molecule often composed of metal oxides, and morphologically similar to a carbon nanotube. Inorganic nanotubes have been observed to occur naturally in some mineral deposits....
- DNA nanotube
- Membrane nanotubeMembrane nanotubeMembrane nanotubes, membrane nanotubules or cytonemes are long and thin tubes formed from the plasma membrane that connect different animal cells over long distances. Two types of nanotubes have been observed. The first type are less than 0.7 micrometres in diameter, contain actin and carry...
