In vitro antimicrobial properties of MeHA/ELP-ZnO hydrogels with different ZnO concentrations. Representative SEM images of methicillin-resistant Staphylococcus aureus (MRSA) colonization on hydrogels containing (a, b) 0% ZnO, (c, d) 0.1% ZnO, and (e, f) 0.2% ZnO. Clusters of bacteria are shown in dashed circles. (g) Representative live/dead images from bacteria seeded hydrogels containing (g) 0% ZnO, (h) 0.1% ZnO, and (i) 0.2% ZnO after 1 day of incubation. (i) Colony counting results of different ZnO concentrations in ZnO/HA-ELP hydrogels. Hydrogels were formed by using 2% MeHA and 10% ELP at 120 s UV exposure time (** p < 0.01).
