OverviewTypesDefinitionSourcesApplicationsSynthesisCharacterizationUniformity

Nano-objects are often categorized as to how many of their dimensions fall in the nanoscale. A nanoparticle is defined a nano-object with all three external dimensions in the nanoscale, whose longest and the shortest axes do not differ significantly. A nanofiber has two external dimensions in the nanoscale, with nanotubes being hollow nanofibers and nanorodsbeing solid nanofibers. A nanoplate has one external dimension in the nanoscale, and if the two larger dimensions are sig
