A) Protein adsorption of PNAGA hydrogel, PNAGA‐PSBMA‐10‐4 hydrogel, and PNAGA‐PCBAA‐b‐4 (b = 10, 15, and 20) hydrogels. PNAGA‐PCBAA hydrogels exhibited significantly lower protein adsorption compared to PNAGA hydrogel and PNAGA‐PSBMA‐10‐4 hydrogel (p* < 0.05), and no significant difference was observed among the PNAGA‐PCBAA hydrogels. B,C) Micrographs of histological sections stained with H&E and M&T after 1 month implantation of PNAGA hydrogel and PNAGA‐PCBAA‐10‐4 hydrogel. Hydrogels were located on the left side of the images which were denoted by red arrows. B3,B4) Inflammation regions and C3,C4) fibrosis regions were indicated by green arrows. The scale bars are 500 µm (4×) and 100 µm (20×).
