How are Nanomaterials Classified Based on Dimensions?
Nanomaterials are classified based on the number of dimensions that fall within the nanoscale range:
1. Zero-Dimensional (0D) Nanomaterials: These are materials where all dimensions are within the nanoscale, such as nanoparticles and quantum dots. 2. One-Dimensional (1D) Nanomaterials: These have one dimension outside the nanoscale, such as nanorods and nanotubes. 3. Two-Dimensional (2D) Nanomaterials: These have two dimensions outside the nanoscale, such as nanosheets and nanocoatings. 4. Three-Dimensional (3D) Nanomaterials: These are bulk materials composed of nanoscale units, such as nanocomposites and nanoporous materials.
