Fig. 4 Forces extracted from simulations as function of contour length of dsDNA in sensor. Three conditions are considered in the simulations, namely, that without kink structure in dsDNA but with a fork at the junction of dsDNA and ssDNA, that with kink structure in dsDNA but without a fork at the junction of dsDNA and ssDNA, and that with kink structure in dsDNA and a fork at the junction of dsDNA and ssDNA. NN base pair stacking interaction $\Delta\xi$ and excited energy $\mu$ used in simulations are $1.3k_{B}T$ and $8k_{B}T$, respectively.
