« … Human health has always been
determined on the nanometer scale; this is
where the structure and properties of the
machines of life work in every one of the
cells in every living thing. The practical
impact of nanosciences on human health
will be huge ».

• A nanometre is a unit of length in
the metric system, equal to one
billionth of a meter (i.e., 10-9 m or
one millionth of a millimetre)
A nanometre is approx 1/100 000th
of a human hair
