Results of the in vivo degradation study of AuNP‐containing hydrogels (PF‐A + AuNPs and PF‐A formulations). a) MRI scans of the mouse injected with PF‐A + AuNPs: white arrows indicate the hydrogel lumps. b) In vivo degradation profile of the two formulations (PF‐A + AuNPs and PF‐A), n = 6, paired Student's t‐test, p < 0.05 (*) and < 0.005 (**). c) No change was noted in the body weight of mice over a 14‐day course, n = 6. The data are presented as mean ± SD.
