Root Explanation

Nanoparticle → It is formed from "nano-" (from Greek "nanos", meaning dwarf or very small) and "particle" (from Latin "particula", meaning a small part). The word "nanoparticle" refers to a very small particle, typically in the size range of 1 to 100 nanometers.

Memory Tip

Think of 'nano-' meaning very small, like a dwarf, and 'particle' meaning a small part. This helps you remember that a nanoparticle is a tiny particle.
