Here the upper trap is steered upwards slowly during stretching and then quickly back again for the next stretching-curve(no DNA-physics in that). It's not possible get the sequence from the force-extension curve. The curve is well described by the worm-like-chain model for polymers. Other labs have done unzipping experiments where a DNA or RNA hairpin is unfolded. There it is possible to see a difference between AT and GC base-pairs, but single base-pair spatial resolution is very challenging.
