"Nanometer precision" refers to the ability to accurately measure or control something with a very high level of detail at the scale of one billionth of a meter. It means being extremely precise and exact at a very tiny scale. Full definition
To accomplish this, Xie's group has developed several strategies to achieve single - molecule sensitivity with high specificity, millisecond time resolution, and nanometer precision in living cells. (kavlifoundation.org)
