Nanomaterials research takes a materials types of nanomaterials pdf-based approach to nanotechnology, leveraging advances in materials metrology and synthesis which have been developed in support of microfabrication research. Materials with structure at the nanoscale often have unique optical, electronic, or mechanical properties. Nanomaterials are slowly becoming commercialized and beginning to emerge as commodities.
Material with any external dimension in the nanoscale or having internal structure in the nanoscale. Nanoscale” is, in turn, defined as: “Size range from approximately 1 nm to 100 nm.
Engineered nanomaterials have been deliberately engineered and manufactured by humans to have certain required properties. Legacy nanomaterials are those that were in commercial production prior to the development of nanotechnology as incremental advancements over other colloidal materials.
