Sticky model finds higher unbound probability for cartilage stress-relaxation at higher salt concentrations. These findings provide experimental validation of the mechanisms proposed by the sticky model. (A) Ensemble average stress-relaxation data in 0.15M (blue) and 1M (red) NaCl. (B) Representative sticky model curvefits to 0.2-100 s of cartilage stress-relaxation. (C) For n=8 samples, the sticky model found higher unbound probability in 1M NaCl compared with 0.15M NaCl (p=0.018). (D) Ensemble average data in 0.075M (blue) and 0.5M (red) CaCl2. (E) Representative sticky curvefits from 0.2-100 s of stress-relaxation. (F) For n=8 the sticky model found unbound probability on 0.5M CaCl2 compared with 0.075M (p=0.009).
