| Abstract | Nanomaterials fabrication methods can be classified according to whether their assembly followed either the so called bottom-up approach or the top-down approach. The bottom-up approach is one where smaller components of atomic or molecular dimensions self-assemble together, according to a natural physical principle or an externally applied driving force, to give rise to larger and more organized systems. The top-down approach is where a process starts from a large piece and subsequently uses finer and finer tools for creating correspondingly smaller structures. These two approaches for fabricating nanomaterials are briefly reviewed in this paper. The paper is an attempt to illustrate the main principles characterizing the two approaches to nanotechnology. On the top-down side, we consider the description of radiation and non-radiation based lithography methods used for fabricating electronic nano-devices; on the bottom-up side we refer to the self-assembly methodology to fabricate polymer nanostructures. |
