One
opportunity for nanoscale
filters is for the separation of molecules,
such as proteins
or DNA, for research in genomics.
See Selective nanofilters for proteins,
DNA Another, as "masks
to prevent exposure to biological pathogens such as viruses that can be as
small as 30 nanometers
in diameter." See Biologically inspired nanotechnology. And another use is in water
filtration. See Softer, Purer Water.
