What you need to know

Define nanoscience in terms of the scale of particles (1–100 nm).
Compare nanoparticles to fine particles (PM2.5) and coarse particles (PM10).
Explain the relationship between side length and surface area to volume ratio in cubes.
Explain how properties of nanoparticles differ from bulk materials due to high surface area to volume ratio.
