What are the Size Classifications in Nanotechnology?
Materials in nanotechnology can be classified based on their dimensions:
Zero-dimensional (0D): Structures such as nanoparticles where all three dimensions are in the nanoscale range. One-dimensional (1D): Structures like nanowires and nanotubes with one dimension outside the nanoscale range. Two-dimensional (2D): Structures such as nanosheets and thin films where two dimensions are in the nanoscale range. Three-dimensional (3D): Structures like nanoporous materials with all three dimensions at the nanoscale level.
