(top panel) Potential of mean force (PMF) 𝒲tether, in units of kBT, as a function of the tether length ℒtether. The PMF shows three distinct scaling regimes — an initial linear regime followed by a quadratic regime which crosses over to a final linear regime—and the scaling relations are also shown alongside. (bottom panel) The force ℱtether, in units of pN, required to extract the tether
