Biocompatibility and antibacterial properties of hydrogels. Cell viability of NIH/3T3 co-cultured with hydrogel extracts for A 12 h and 24 h. and B 1d, 3d and 5d. C Hemolytic activity assay of HP and HP-AgM hydrogel. Inset is the corresponding photograph. D Photographs of survival bacteria colonies (S. aureus, white dots in plates) growing on agar plates after direct contact incubation with HP and HP-Ag hydrogels. PBS was used as control. E OD values at 600 nm of S. aureus solution co-cultured with the hydrogels for 12 h and 24 h. All data are presented as mean ± SD, n = 4, **p < 0.01, ***p < 0.001, ****p < 0.0001
