a) Depiction of the sequential fabrication procedure used to fabricate the cylindrical bilayered hydrogels by exploiting a PDMS mold. b) Mechanical analysis of the bilayered hydrogels after 30 d incubation in PBS and H₂O₂ in terms of: Young's modulus, fracture stress, fracture strain and toughness. c) Analysis of the total mass variation overtime, upon incubation in PBS and H₂O₂. Data are presented as mean ± SD, n = 4, p‐values are calculated using the one‐way ANOVA with Tukey's post‐test correction, * p < 0.05. Analyzed sample: full cartilage‐mimicking bilayered hydrogel composed of GG/PEGDA10_5 minUV_10 minMgCl₂ (bottom part) and GG/PEGDA10/GO_5 minUV_10 minMgCl₂ (top part).
