A nanotube is a
nanometer-scale hollow tube-like structure.
Kinds of nanotubes
*
BCN nanotube
BCN nanotubes are tubular structures with a sub-micrometer diameter and a length much longer than diameter. They are composed of comparable amounts of boron, carbon and nitrogen atoms.
First made in 1994, synthesis methods have included: arc-disc ...
, composed of comparable amounts of
boron, carbon, and nitrogen atoms

Boron nitride nanotube
Boron nitride nanotubes (BNNTs) are a polymorph of boron nitride. They were predicted in 1994 and experimentally discovered in 1995. Structurally they are similar to carbon nanotubes, which are cylinders with sub-micrometer diameters and micromete ...
, a polymorph of boron nitride

Carbon nanotube, includes general nanotube terminology and diagrams
*
DNA nanotube, a two-dimensional lattice which curves back upon itself,
somewhat similar in size and shape to a carbon nanotube
*
Gallium nitride nanotube
Gallium is a chemical element with the symbol Ga and atomic number 31. Discovered by French chemist Paul-Émile Lecoq de Boisbaudran in 1875, Gallium is in group 13 of the periodic table and is similar to the other metals of the group (aluminiu ...
, a nanotube of gallium nitride
*
Silicon nanotube
Silicon is a chemical element with the symbol Si and atomic number 14. It is a hard, brittle crystalline solid with a blue-grey metallic luster, and is a tetravalent metalloid and semiconductor. It is a member of group 14 in the periodic tab ...
, made of silicon atoms
*
Non-carbon nanotube
A non-carbon nanotube is a cylindrical molecule often composed of metal oxides, or group III-Nitrides and morphologically similar to a carbon nanotube. Non-carbon nanotubes have been observed to occur naturally in some mineral deposits.
A few year ...
, especially
tungsten(IV) sulfide nanotubes

Tunneling nanotube
A tunneling nanotube (TNT) or membrane nanotube is a term that has been applied to protrusions that extend from the plasma membrane which enable different animal cells to touch over long distances, sometimes over 100 μm between T cells. Two t ...
, a tubular membrane connection between cells

Titanium nanotubes, created by the conversion of the mineral anatase by hydrothermal synthesis
