The antibacterial activity of the hydrogel. a Photos of S. epidermidis and E. coli. solution co-cultured with the hydrogels after 1 day. b The bactericidal ratio of the hydrogels to S. epidermidis and E. coli. (Error bar means the standard deviation, * indicates statistically difference at p < 0.05, p value was generated by one‐way analysis of variance (ANOVA), followed by Tukey's multiple‐comparison post hoc test, n = 3). c Scheme of the in vivo antibacterial experiments. d Photographs of harvested hydrogels after they were implanted in the skin pockets for 7 days of post surgery. e Hematoxylin–eosin (H&E)-stained sections of connective tissues surrounding the hydrogel
