Fig. 13 — (a) Graphical representation showing the mode of action of AgNP/GelMA hybrid hydrogels. (b) Percentage of wound closure quantified as a function of time (c) Percentage of wound healing quantified after 24 h (d) Antibacterial action of 15% AgNP/GelMA formulation against E. coli and S. aureus characterized by quantifying the change in absorbance. (e) Schematic model of in-vitro wound healing scratch assay performed on GelMA using a PDMS device.
