Nanotopography and Nanolithography

Nanotopography refers to the specific surface features which appear on the nanoscale.In industry, applications of nanotopography typically encompass electrics and artificially produced surface features. However, natural surface features are also included in this definition, such as molecular-level cell interactions and the textured organs of animals and plants. These nanotopographical features in nature serve distinctive purposes that aid in regulation and function of the biotic organism, as nanotopographical features are extremely sensitive in cells.Nanolithography is the process by which nanotopographical etchings are artificially produced on a surface. Many practical applications make use of nanolithography, including semiconductor chips in computers. There are many types of nanolithography, which include:PhotolithographyElectron beam lithography (EBL)
