(a) Force and (b) deformation experienced by the ATM during the compression of stacked gels in which a Ge₂₀ layer was paired with another gelatin layer (Ge₂₅, Ge₃₀, Ge₄₀, or Ge₆₀); (c) force and (d) deformation experienced by the ATM during the compression of stacked gels in which an Ag₂₀ layer was paired with another agar layer (Ag₂₅, Ag₃₀, Ag₄₀, or Ag₆₀). The envelopes around the thick colored lines show the standard deviations obtained from seven replicates.
