a Schematic illustration of CPAMC/PCA Janus hydrogel. b The FT-IR of CPAMC hydrogel and PCA hydrogel. c The conductivity analysis of CPA/PCA, CPAM/PCA, and CPAMC/PCA Janus hydrogel (error bar means the standard deviation, *p < 0.05, **p < 0.01, ***p < 0.001, p value was generated by one‐way analysis of variance (ANOVA), followed by Tukey’s multiple‐comparison post hoc test, n = 3 independent samples). d The SEM of CPAMC/PCA hydrogel. e Adhesion analysis of CPAMC side and PCA side of CPAMC/PCA Janus hydrogel. f The recruitment results of RAW 264.7 cell in culture plate (plate), CPAMC hydrogel, and PCA hydrogel. g The statistic analysis of recruitment of RAW 264.7 cell in culture plate (plate), CPAMC hydrogel, and PCA hydrogel (error bar means the standard deviation, *p < 0.05, **p < 0.01, ***p < 0.001, p value was generated by one‐way analysis of variance (ANOVA), followed by Tukey’s multiple‐comparison post hoc test, n = 5 independent samples). CAP, CPAM, CPAMC: C, aldehyde cellulose (CNC-CHO); P, polyethylenimine (PEI); A, acrylic acid; M, 3-sulfonic acid propyl methyl acrylic acid potassium (MASEP); C, caffeic acid (CA). PCA: P, polyethylene glycol diacrylate (PEGDA); C, carboxylated cellulose (CNC-COOH); A, acrylic acid.
