Nanopore Illustration (IMAGE) University of Texas at Dallas Caption In this illustration, a single-stranded DNA molecule moves through a nanopore. The nanopore is about 2 nanometers (nm) in diameter. By comparison, a strand of human hair is 80,000 to 100,000 nm wide. A water shell (blue) surrounds the DNA strand.
