A Hemolysis ratios of RBCs with images of RBCs (inset) after the hydrogels incubated with RBCs for 2 h at 37 °C with shaking. The redness indicates that the RBCs were destroyed and hemoglobin was released. (+) represents positive control, and (−) represents negative control; Cell viability (B) and fluorescent staining (C) of 3T3 cells on hydrogel; GO-PAM (a), HEP20-rGO-PAM (b), PDA0.8-rGO-PAM (c), HEP20-PDA0.2-rGO-PAM (d), HEP20-PDA0.4-rGO-PAM (e), HEP20-PDA0.8-rGO-PAM (f)
