Nanomaterials can be categorized based on their dimensions:
Zero-dimensional (0D): These are nanoparticles where all three dimensions are in the nanoscale range. Examples include quantum dots and fullerenes. One-dimensional (1D): These include materials such as nanowires and nanorods, where one dimension is significantly larger than the other two. Two-dimensional (2D): Examples are graphene and nanosheets, where two dimensions are in the nanoscale and the third is larger. Three-dimensional (3D): These include materials like nanocomposites, which have three larger dimensions but contain nanoscale features within them.
