Nanotechnology is a scientific field that uses system or component development techniques to build products on highly granular levels. Nanotechnology works through different approaches to build nano materials or products, including bottom-up, top-down and functional system development. In a bottom-up approach, a product is designed as it evolves from its tiniest form factor to larger product.
