Force vs ΔL plot (left), unfolding force histograms (middle), and ΔL (right) histograms of the (dA)₂₁ containing DNA constructs in the presence of AuNPs with diameters of A) 1.8 nm, B) 5.0 nm, and C) 10.0 nm. Dotted curves in the blown-up insets in the unfolding force histograms represent the gaussian fits for individual populations. Solid curves are Gaussian fittings for overall populations. N represents the number of molecules from which the FX curves were collected, and n represents the total number of unfolding features measured.
