(a) Stress–strain behaviour for disulfide gels with different compression speeds and (b) failure strain–stress points for experiment and simulation. (c) Fluorescence intensity of gels containing different fractions of PEGDA and 4arm-PEG-thiols in the presence of fluorescein-5-maleimide,and (d) representative laser scanning confocal microscope images of these hydrogels when exposed to 40% compression. (*P < 0.05, #P < 0.01,t-test).
