Carbon has been used extensively on the nano scale for such things as nanotubes, lipid nanodiscs, and semiconductors, among other things.

Carbon nanotubes are special type of nanotube made only of carbon. These are very durable and good conductors of heat due to their extensive #sp^2# hybridization. Here's an example model:

Lipid nanodiscs are phospholipid bilayers (fatty acids containing carbon, phosphoryl, and nitrogenous compounds) intended to imitate membranes.

These are constructed as integral membrane proteins surrounded by #alpha#-helical proteins (made up of amino acids, which are made of carbon, and amino and carboxyl groups) that bind the structure together, restricting its size to the nano scale.

Graphene nanoribbons are a good example of carbon semiconductors. They are linear expansions of benzene rings in the vertical and horizontal direction, forming either ribbons or sheets. Their HOMO-LUMO gaps are small, allowing for good conductivity.

Their arynes have biradical character (two radical electrons that can move independently of each other), allowing for greater conductive capabilities.
