      A nanoparticle is an extremely small particle which size is at the nanoscale. The word “nano” comes from the Greek word for dwarf. For you to have an idea on how tiny a nanoparticle is, a nanometer is a billionth of a meter. For to you to picture it better, a tennis ball is to the earth what a nanoparticle is to a tennis ball.
