Which of the following ranges of particle size defines nano scale ?
- A$10\text{-}100$ nm
- B$1000\text{-}2000$ nm
- Correct answerC$1\text{-}100$ nm
- D$100\text{-}1000$ nm
Solution
Nanoscale is defined as the size range from $1$ nm to $100$ nm.
Particles with at least one dimension in this size range are considered nanoparticles.
Answer: $1\text{-}100$ nm
Particles with at least one dimension in this size range are considered nanoparticles.
Answer: $1\text{-}100$ nm
