    • Multiple attractive peaks were also observed in some experiments. We attribute these types of curves to single polymer chains which became adsorbed to the tip at multiple sites, i.e., the formation of adsorbed chain loops on the tip

    • We also conducted experiments as a function of strain rate (controlled by dz/dt, the z-piezo deflection rate) and found no influence over 2 orders of magnitude on the single chain entropic elasticity force profiles on retraction and subsequent calculations of a.
