A Changes in storage modulus (G′) and damage modulus (G″) of PADM or AgNP–PADM hydrogels over time at neutral pH. B Porosity of PADM and AgNP–PADM hydrogels prepared using 20, 50, and 80 μg mL^− 1 AgNP solutions. All PADM and AgNP–PADM hydrogels exhibited negligibly different porosities. C PADM and AgNP–PADM hydrogel prepared using 80 μg mL^− 1 AgNP solution exhibited negligibly different water retentions. D PADM and AgNP–PADM hydrogels prepared using 80 μg mL^− 1 AgNP solution and subsequently degraded at 25, 37, and 42 °C. E PADM and AgNP–PADM hydrogels prepared using 80 μg mL^− 1 AgNP solution and subsequently degraded with or without trypsin. F AgNP release for PADM and AgNP–PADM hydrogels prepared using 80 μg mL^− 1 AgNP solution and degraded at 25, 37, and 42 °C. G AgNP release of PADM and AgNP–PADM hydrogels prepared using 80 μg mL^− 1 AgNP solutions and subsequently degraded with or without trypsin. H AgNP release for PADM and AgNP–PADM hydrogels prepared using 80 μg mL^− 1 AgNP solution and subsequently ultrasonically oscillated. All values are presented as mean ± standard deviation
