Nanomaterials and Applications

Nanomaterials are materials that are composed of nanoparticles having a size ranging from 1 to 100 nm. The constituent particles are 100,000 times smaller than the thickness of a strand of human hair. The nanoparticles cannot be seen through naked eyes and require very high-resolution microscopes. Here, 'nm' stands for nanometer. These materials can occur naturally or can be artificially made. Artificially made nanomaterials are often called lab-engineered nanomaterials. Nanomaterials are extensively used in electronics, medical, aerospace, and other industries.
