nanomaterial nanotechnology

Nanomaterials are the nanoscale materials: materials with structural features (particle size or grain size, for example) of at least one dimension in the range 1-100 nm.

Nanomaterials in nanotechnology are created to make bigger materials with desired properties. But, although nanotechnology implies working at and understanding matter at the nanoscale, the ultimate aim of nanotechnology is to make improvements to existing large-scale systems, processes and products.

Nanomaterial creation in nanotechnology starts with atoms and the ability to predict their reactions, behaviors and interactions to form small molecules.

Nanomaterials are the building blocks of nanotechnology. Here are some of already known.

Nanotubes - tubes made of carbon atoms (sometimes with other elements such as boron) linked together in rings of six to form hexagons. Flat sheets of hexagons are then joined together and rolled up to make a hollow tube.

Nanowires - similar in many ways to nanotubes, but with even more pronounced electrical and conducting or insulating properties.

Nanocomposites/Nanoparticles - essentially any small spherical structure with a diameter not exceeding 100 nanometers. Can be single or bind together into clusters, cones etc. Can be made from a variety of materials - carbon, metallic elements, ceramics, drugs etc.
