Representative normal force, F_⊥ (normalized by the radius of curvature R) as a function of mica–mica separation distance, D. Comparison of (a) native- to recombinant-based coacervate adhesion/cohesion profiles: mcfp-1/HA 1:1 ratio (black), rmfp-1/HA (blue), and rmfp-1-Dopa/HA (red). Comparison of (b) mcfp-1/HA coacervate adhesion/cohesion profiles at varying mixing ratios: mcfp-1/HA 7:3 ratio (teal), mcfp-1/HA 1:1 ratio (black), and mcfp-1/HA 3:7 ratio (purple). The hardwall is defined as the minimum separation observed under compression for the given normal force measurement. Forces measured on approach are indicated by solid circles and on separation by open circles. Jump-out during separation indicates mechanical instability, whereas dissipative-bridging interactions indicate continuous interaction during separation.
