Having
one or more Euclidean spatial dimensions typically in the range of 100 nm or
less, i.e. From the (macro) molecular
down to the atomic scale, but excluding the subatomic scale.
Significantly
smaller than a micron;
on the scale of large molecules;
capable of interacting with molecules;
capable of being built by a single assembler.
Concerning
the molecular
and macromolecular level. Generally, the nanoscale is defined from 1 to 100
nm, whereas the range from 100 to 1000 nm is named the submicrometer scale.
