Title: Nanometrology, molecular rulers
Description: Graphic depicting how the ice fishing method determines the distance across a membrane nanopore. Both images show DNA strands of known lengths topped by a polymer cap (orange sphere) being driven through the nanopore. If the DNA strand is long enough to completely transverse the channel (left), it will hook a circulating polymer (green sphere) on the other side of the membrane and define the nanopores length. If not long enough, the DNA probe will bounce out of the pore (right).
