A, B Viability of HeLa cells cocultured with PADM and AgNP–PADM hydrogels for 48 h. C CCK-8 method was used to detect effects of PADM and AgNP–PADM hydrogel immersion on cell viability. D Free-radical scavengabilities of ascorbic acid, PADM, and AgNP–PADM hydrogels in range 50–250 μg mL^− 1. E IC₅₀ values of ascorbic acid, PADM, and AgNP–PADM hydrogel groups IC50: the 50% inhibiting concentration
