nanoparticle

noun    (Concise Encyclopedia)

Ultrafine unit with dimensions measured in nanometres (nm; billionths of a metre). Nanoparticles possess unique physical properties such as very large surface areas and can be classified as hard or soft. They exist naturally in the environment and are produced as a result of human activities. Manufactured nanoparticles can have various compositions and thus may have practical applications in a variety of areas, ranging from environmental remediation to engineering and medicine. Examples of naturally occurring nanoparticles include terpenes released from trees and materials emitted in smoke from volcanic eruptions and fires. Quantum dots and nanoscale zero-valent iron are examples of manufactured nanoparticles.
