CLASSIFICATION OF NANO MATERIALS
Nanomaterials can be classified on the basis :
Orgin
Dimensions
Structurals configuration
According to Orgin:
Natural nanomaterials:
Examples are Viruses, Protein, molecules etc. Few other examples are minerals su
natural colloids, such as milk and blood (liquid colloids), fog (aerosol type), gelatin
mineralized natural materials such as shells, corals and bones, insect wings and opals
lotus leaf ,Gecko’s feet, volcanic ash, ocean spray etc.
Artificial nanomaterials:
Artificial nanoparticles are those which are prepared by well defined mechanical a
fabrication process.
Examples: carbon nanotubes, semiconductor nanoparticles like quantum dots etc.
, On the basis of the dimensions
Zero-dimensional nanomaterials:
All dimensions (x, y, z) are at nanoscale, i.e., no dimensions are greater
nm.
It includes nanospheres and nanoclusters.
