Fig. 7.
Trajectory of the center of mass of a λ-DNA molecule at 10 V/cm. The λ-DNA is highly extended and does not always have enough time for complete relaxation before next collision, which for this particular trajectory results in reptation through the 2nd nanofence array. Five images of a λ-DNA during migration in the nanofence array are included, with the direction of motion being from left-to-right. The DNA moves at constant free solution migration velocity before and after collisions (blue dotted lines). Scale bars = 10 μm.
