Bulk + Surface Properties of Matter Including Nanoparticles

What is nanoscience?

Science that studies particles that are 1 - 100 nm in size

State the uses of nanoparticles

Medicine (drug delivery systems), Electronics, Deodorants, Sun creams (better skin coverage and more effective protection against cell damage)

What are fine and coarse particles?

• Fine particles (soot): 100-2,500 nm diameter

• Coarse particles (dust): 2,500-10,000 nm diameter

Why do nanoparticles have different properties to those for the same materials in bulk?

Due to their high surface area to volume ratio.

What are nanotubes?

Nanotubes are cylindrical fullerenes with a high length to diameter ratio.
