Multiple choice

Which of the following approaches of preparing nano-structured materials make(s) use of techniques of colloidal chemistry to pattern materials?

  1. Top-down approach

  2. Bottom-up approach

  3. Both (1) and (2)

  4. Neither (1) nor (2)
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

This option is correct because bottom-up approach employs various techniques of colloidal chemistry because of which nanostructures are formed in parallel and can sometimes be nearly identical, but usually have no long range order.
