Nanomaterials are materials whose characteristic length scale lies within the nanometric range (1-100nm)at least in one dimension. The word 'nano ' has the origin from the Greek meaning 'Dwarf '.lt is one billionth of a metre.                                                                   Nanomaterials are objects with any one of the three external dimensions at the nanoscale. Nanoparticles that are naturally occuring or are the incidental byproducts of combustion processes are usually physically and chemically heterogeneous and often termed ultrafine particles.                                                 Engineered nanomaterials are intentionally produced and designed with very specific properties related to shape, size, surface properties and chemistry. These properties are reflected in aerosols, colloids, or powders. Often, the behavior of nanomaterials may depend more on surface area than particle composition itself.
