Nanomaterials are one of the main objects or structures that are designed and produced by Nanotechnologies at the size level of approximately 1-100 nanometers. Nanomaterial research is a field that takes a materials science-based approach on nanotechnology. Nanoparticles are objects with all three external dimensions at the nanoscale. Nanoparticles that are naturally occurring or are the incidental byproducts of combustion processes are usually physically and chemically heterogeneous and often termed ultrafine particles. Engineered nanoparticles 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.
