A nanomaterial is one having at least one dimension in the range
Answer: A
Correct answer: 1 to 100 nanometres
The upper bound is a convention rather than a physical boundary, but it is chosen because the size-dependent effects that make nanomaterials interesting - quantum confinement, the dominance of surface atoms, plasmon resonance - become appreciable below roughly a hundred nanometres. A nanometre is a thousand-millionth of a metre, about four atoms across.
