The average volume fractions of the grafted ssDNA chains as a function of distance from the nanoparticle surface at different temperatures for (a) N = 30, (b) N = 20, and (c) N = 10. The insets show the degree of dissociation as a function of distance from the nanoparticle surface. (d) The height of grafted ssDNA layer as a function of temperature for different N. The grafting density is σ = 0.5 nm⁻².
