Fig. 1. Characterization of the PLLA-PDA-CD40mAb scaffold. (a) The cartoon of PLLA electrospun fibrous scaffolds with the antibody grafted through PDA. (b) The morphologies of the different scaffolds under a SEM. (The insets present contact angles, which represent the polar properties of the scaffolds.) (c) XPS. (d) Stress–strain curves. (e) WCA (compared with the PLLA group *p < 0.05).
