Fig. 3: Peptide chains stabilize coacervates towards deformations outside of the linear viscoelasticity regime.

a Stress-strain curve obtained from a tack experiment of different coacervates. b Work of adhesion, obtained from calculating the area under the curve from the stress-strain curve. The data reported for the work of adhesion is the average of three independent measurements, and the error bar corresponds to the standard deviation. Individual data points are shown as dots.
