Nanotube
# Nanotube

A nanotube is a nanometer-scale hollow tube-like structure.

## Kinds of nanotubes

* BCN nanotube, composed of comparable amounts of boron, carbon, and nitrogen atoms
* Boron nitride nanotube, 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, a nanotube of gallium nitride
* Silicon nanotube, made of silicon atoms
* Non-carbon nanotube, especially tungsten(IV) sulfide nanotubes
* Tunneling nanotube, a tubular membrane connection between cells
* Titanium nanotubes, created by the conversion of the mineral anatase by hydrothermal synthesis
