Characterization of the hydrogel system. a Photographs of the solution to hydrogel transition by photocuring and the stability of hydrogel was proved by placing in different orientations. b Adhesion and bending ability on different surfaces. c Representative SEM images showed the interconnected porous meshwork of Sil-MA and M@M–Ag–Sil-MA scaffolds (Scale bar: 50 μm). The black and red arrows represent MET@MSNs and Ag NPs encapsulated in hydrogels, respectively. Storage modulus (G′) surpassing the loss modulus (G″) and at different d time (lasting for 100 s) and e frequencies (from 65 to 255 Hz). f–h Swelling property of hydrogel system containing different components under the PBS with different pH values (pH = 6.0/7.4/8.0). i–k Degradation property of the different hydrogel system soaked into PBS until complete swelling under different pH values (pH = 6.0/7.4/8.0)
