The elasticity of dextran and pustulan is not affected by solvents. We compare the experimental force-extension curves for pustulan (A) and dextran (B) obtained in water (black traces) and in solvents with a low dielectric constant (ɛ) (red traces). (A) The red trace represents the force curve for pustulan obtained in dimethyl carbonate (ɛ = 3.1). (B) The red trace represents the force curve for dextran obtained in ethanol (ɛ = 25).
