(a) Hyperbolic contraction similar to the system in Figure 75. (b) Illustration of the experimental protocol for creating a gel near the entrance to the hyperbolic contraction. (c) Images of the DNA extension as it crosses from the gel into the fluid before the hyperbolic contraction. The solid line indicates the location of the gel/fluid interface.
