Topic Summary: Nanoparticles
Key Terms
- Nanoparticle: 1-100 nm particle with different properties from bulk
- Surface area to volume ratio: increases as particle size decreases
- Fullerene: hollow carbon cage (C₆₀) — used in drug delivery
- Graphene: single layer of graphite — strong conductor
- Nanotechnology: design and use of nanoscale materials
Must-Know Facts
- 1 nm = 10⁻⁹ m (one billionth of a metre)
- Nanoparticles have high surface area to volume ratio
- More reactive than same material in bulk form
- Uses: sunscreen, catalysts, antimicrobials, drug delivery, electronics
- Safety concerns: effects on human health not fully known
- Fullerenes: hollow carbon molecules, simple molecular structure
